State population and household estimates,with age,sex, and components of change: 1981-87

This report contains provisional US state estimates of 1) the resident and civilian populations and of households for July 1, 1987, 2) revised annual population and household estimates for July 1, 1981-1986, and 3) components of population change for the 1980-1987 period. Also shown are annual age estimates and median age of the resident population of states, 1981-1987, by sex for 10-year age groups and selected broad age groups. Florida passed Pennsylvania to become the 4th most populous state in 1987, ranking behind California, New York, and Texas. Alaska and Louisiana both registered population losses for the 1st time this decade, while West Virginia, Oklahoma, and Wyoming again had population declines. Several agriculture-based states--Iowa, North Dakota, and Nebraska--marked another year of population declines. California and Florida each gained more than 2 million persons through net immigration since 1980, and Texas over 1.2 million. The 25-44 year-olds are the most rapidly growing age group in the 1980s, increasing by 23.8%. This age group now constitutes almost 1/3 (31.9%) of the US population. US median age continues to climb upward, increasing from 30 years in 1980 to 32.1 years in 1987. The Northeast continues as the region with the highest median age (33.7) and the highest proportion of elderly (13.5% aged 65 and over). Largely because of changes in the age structure, households increased faster than the total population from 1980-1987 (12% versus 7.4%). The 4 states that lost population between 1980 and 1987--Ohio, Michigan, Iowa, and West Virginia--all had increases in households during the same period. While the Northeast and Midwest together accounted for only 10.8% of national population growth in the 1980-1987 period, they accounted for 26.9% of the national increase in households. California, Texas, and Florida accounted for 52.4% of national population growth from 1980 to 1987, but only for 36.5% of household growth.     

Macro and micro contexts of dependency rates: An illustration with peruvian data

This research contributes to the academic dialogue about the socioeconomic significance of rapid population growth by examining changes in age composition and household structure during a transitional period of demographic change. Two propositions relating changes in the size and age composition of households to the demographic transition are formulated and tested using Peruvian census and survey data. Results show a systematic pattern of change wherein the average annual percent increase in the number of households offsets the rate of population growth when the disequilibrium between mortality and fertility rates is greatest. The translation of aggregate increase into households is mediated by shifts in the distribution of households by size. It is inappropriate to conclude that larger families necessarily have higher dependency burdens or that they are worse off in an economic sense compared to smaller households because increments in size are not automatically translated into equivalent increases in age or economic dependency. In part, this is due to the influence of extension patterns on the age and labor force composition of households. Policy implications and a research agenda are discussed in the concluding section.An earlier version was presented at the 7th National Meeting of the Latin American Studies Association, Houston, Texas, November 2–5, 1977. I gratefully acknowledge critical comments from Michael E. Conroy, Harley L. Browning, A. Eugene Havens, Halliman Winsborough, and two anonymous reviewers.

Nativity,duration of residence and the life course pattern of extended family living in the USA

Recent changes in US immigration policy anddomestic welfare policies affecting immigrants haveled to concerns that families will face greaterpressure to provide for extended family members.Extended family households are important resources fornew immigrants to the USA and an integral part of theadaptive strategy of immigrants. This paper examinesthe competing roles of duration of residence in theUSA, aging and changes over time in explainingincreases in extended family living between 1980 and1990. The results from a pooled sample of 1980 and1990 Census data indicate that recent arrivals aremore likely to share households with extended kin butit is older immigrants who face an increasedlikelihood of such coresidence over time. Multinomiallogistic regression analysis demonstrates that thelife course pattern of coresidence remains whenchanges in socioeconomic status are controlled. Theresults suggest that policy changes limiting publicfunds available to new arrivals will have a largerimpact on families sponsoring older family members.     

American Indian household structure and income

We use the 1980 Public-Use Microdata Sample to consider the relationship between household structure and economic well-being among American Indians. We focus on the total U.S. Indian population and on the residents of 19 "Indian states" where there has been relatively little growth in the Indian population by means of changes in racial self-identification. Using Sweet's (1984) scheme of household types, we find that the prevalence among Indians of female-headed households with children is intermediate between that among blacks and whites, but the prevalence of couple-headed households with children is highest among Indians. Racial differences in the distribution of household types and differences in average household size are important determinants of black-white and Indian-white differences in average household income.     

State and local fiscal impacts of US immigrants: Evidence from New Jersey

This paper uses a household-level estimation strategy to develop new evidence on the state and local fiscal impacts of US immigration. The methodology is applied to 1980 census microdata for New Jersey, a state that now ranks fifth in the nation in the size of its foreign-born population. All New Jersey households combined in 1980 imposed a net fiscal burden on state government of more than US$2.1 billion, and a net burden on the aggregate of all local governments totaling nearly $ 690 million. Both native- and immigrant-headed households received government benefits worth more than they paid in taxes. The typical immigrant-headed household imposed an average fiscal burden of $ 350 on local governments throughout New Jersey, versus roughly $ 225 for each native-headed household. At the state level, however, net fiscal impacts of immigrants and natives were similar: an average annual deficit of $ 841 for immigrants compared with $ 846 for native households. There are larger disparities among the foreign-born population than between native-headed and immigrant-headed households. Latin American households have the most unfavorable fiscal implications of any immigrant subgroup. Taken together, our findings illustrate the overriding importance of household income and number of school-age children as determinants of taxes paid, benefits received and, ultimately, of net fiscal impacts.     

The fall in household size and the rise of the primary individual in the United States

The long-term fall in household size in the United States is discussed within the framework of the aging of the population, continuing as the effects of fertility and mortality decline accumulate. Using distributions of households by size from U.S. census data 1790–1970 and a components of change analysis on primary individuals for 1950–1974, household changes are related to demographic change for the periods 1790–1900, 1900–1950, and 1950–1974. Fertility and mortality declines have unambiguous impact on household size until the increases in primary individuals begin. But these, too, have a theoretically interesting, if indirect relationship to population structure.     

Population growth and air quality in California

Demographers are often interested in the environmental impacts of population growth. I examine the impact of growth specifically on air quality in California. In recent decades, California has suffered from notoriously polluted air and has experienced rapid population growth. Despite the population .growth, air quality actually has improved since the early 1980s due to aggressive regulatory efforts. Using data for 56 counties, I analyze the contribution of population growth to trends in atmospheric emissions of five regulated pollutants from 1980 to 1990, controlling for trends in per capita income and regulatory efforts. The analysis is disaggregated by source of emissions and demonstrates that population growth is strongly associated with some sources of emissions but not with others. Thus, the overall impact of population growth depends upon the composition of production and consumption activities in each county. I also explore whether the trend in number of households predicts better than the trend in number of persons, and whether the impact of population growth depends upon the age structure or source of growth (immigration or domestic increase). Generally, these alternative specifications of population do not improve the models of atmospheric emissions.     

New household projections for the united states

This paper reviews the methods used to prepare the new household projections for the United States that were recently issued by the Bureau of the Census and examines the effect on the resulting number of households of the assumptions made about future marriages and future proportions of household heads in the population.One population projection series was used, since all series are identical for the adult population. Marriage assumptions were generated by assuming various outcomes of the marriage squeeze (defined as the excess of females relative to the number of males in the main ages at marriage in the next few years). Assumptions about proportions of household heads were generated by assuming, in varying degrees, continuation of recent trends in these proportions.Projected changes in marriage and in the proportions of household heads in the population account for one-fourth to one-third of the projected increase in the number of households; the remaining increase is attributable to projected changes in the size and structure of the adult population. Varying the assumed proportions of household heads produces greater differences in the projected total number of households than does varying the marriage assumptions used here. Nevertheless, the various possible outcomes of the marriage squeeze, as represented by the assumptions used, produce significantly different projections of increases in the number of young husband-wife households.The most striking finding is that by 1985, proportions of household heads among the population not "married, spouse present" may well rise to such a level that over the long term, the smaller the number of persons who marry, the larger will be the number of households.     

中国人口年龄结构变动对出生率的影响研究

本文利用相关年份的《中国统计年鉴》和人口普查数据,根据粗出生率与总和生育率的关系与特征,构建了人口年龄结构系数及其对粗出生率变动影响的贡献率指标,分析了建国以来人口年龄结构变动对出生率的影响。研究发现：1949—1979年,人口年龄结构变动对出生率的影响很小;1980—1993年,人口年龄结构变动对出生率的影响迅速上升,年龄结构的贡献率增大;1994—2008年,人口年龄结构变动对出生率的影响趋于下降,人口惯性势能在减弱;2009—2011年,受80—90年代出生高峰的影响,人口年龄结构变动对出生率的影响再次凸显,年龄结构的贡献率迅速增大。从年龄别生育率逐年下降的特点,也可以证明近年推动我国人口增长的力量主要是由于年龄结构带来的惯性增长。     

Racial concentration and segregation across U.S. counties, 1950–1980

By presenting race-specific population concentration indexes for U.S. counties for the 1950-1980 period, this paper updates and extends previous analyses of 1900-1974 patterns of population concentration by Duncan et al. (1961) and Vining and Strauss (1977). Declines in population concentration persisted through 1980 only among the white population. Blacks continued to experience increases in population concentration between 1970 and 1980. These racially divergent patterns of concentration in the 1970s have translated into increases in segregation between blacks and whites across U.S. counties.     

Asian Americans: growth,change, and diversity

The 1980 US census counted 3.5 million Asian Americans, up from 1.4 million in 1970. Asian Americans made up just 1.5% of the total US population of 226.5 million as of April 1, 1980, but this was the 3rd largest racial or ethnic minority after blacks and Hispanics. Asians increased far more during the 1970s (141%) than blacks (17%) or Hispanics (39%). This Bulletin examines the characteristics of Asian Americans, how their numbers have grown, where they live, how different groups vary in age structure, childbearing, health, and longevity. It reports on the kinds of households Asian Americans form and how they fare with regard to education, occupation, and income. Asian Americans are now often perceived as the model minority. As a whole, they are better educated, occupy higher rungs on the occupational ladder, and earn more than the general US population and even white Americans. This Bulletin presents the 1st comprehensive look at many important facts about Asian Americans and how the groups differ. Special tabulations of data collected in the 1980 census are provided. The 1980 census data are the latest available to give a true picture at the national level of Asian Americans and the various groups among them. The Bulletin examines the current numbers of Asian Americans and how this population is defined. The major Asian American groups are Chinese (21%), Filipinos (20%), Japanese (15%), Vietnamese (21%), Koreans (11%), and Asian Indians (10%). Except for the latest-arrived Vietnamese, the fertility of the 6 groups is lower than the white average. The following areas are also discussed: mortality and health; families and households; education; Asian youth; employment; income and poverty; and future prospects.     

Racial differences in per capita income, 1960–76: The importance of household size,headship, and labor force participation

Racial differences in average per capita income are decomposed, as are changes over time for both races. The 1960–76 decline in household size accounted for 13 percent of the per capita income inprovement of both races. Whereas real increases in earnings of husbands contributed most to improvements in well-being in husband-wife households, increases in income from sources other than earnings were most important to female headed households. During a period in which a growing proportion of both races resided in female headed households and racial differences in living arrangements widened, the per capita income of female headed households relative to husband-wife households declined.     

Transfer programs and aggregate household formations

The number of households in the United States increased by over fifty percent in the 1960s and 1970s, nearly double the rate of population growth. Part of the increase is explained by the movement of large cohort groups of the population into prime household-forming age categories, but higher headship rates also contribute. Age-specific headship rate increases result from non-demographic factors, and this paper focuses on the role of government transfer payment programs. Specifically considered are Social Security, Aid to Families with Dependent Children, and Food Stamps. These programs are found to have accounted for as many as 4 million net household formations between 1961 and 1984. The findings have implications for expected households formations in the 1990s.     

Wuxi's pilot population census has laid the foundation for carrying out the Third National Population Census]

In order to lay the foundation for the third national population census, a pilot population census was conducted in Wuxi city, Jiangsu Province in 1980. One goal of this pilot population census was to examine and revise the rules and regulations for the population census. The second goal was to collect practical experience in a population census at a local level, and the third goal was to train a group of working personnel for the national population census. Results from this local population census include information on characteristics of the population, households, and society in general, cultural and educational levels, the economic situation for the local population, marital status, child-bearing status, and the natural mobility of the population. Both the quality and quantity of this pilot population census are excellent. Success is due to an effective and healthy leadership, detailed and well-designed rules and regulations and working principles, support and cooperation from the general public, well-trained working personnel, and suitable use of modern scientific methods for the census.     

Some New Techniques for Applying the Housing Unit Method of Local Population Estimation: Further Evidence

The housing unit method of population estimation is often characterized as being imprecise and having an upward bias. In an earlier paper we argued that the method itself cannot be properly characterized by a particular level of precision or direction of bias. Only specific techniques of applying the method can have such characteristics. In that paper we presented several new techniques for estimating the number of households and average number of persons per household (PPH). However, the testing of these new techniques was limited by the lack of census results against which the estimates could be compared. Complete census data on population, households, and PPH are now available and can be used to test alternate estimation techniques. In this paper we replicate the tests reported in our earlier paper using 1980 census data for Florida’s 67 counties. These tests provide further evidence that the new techniques produce more precise, less biased estimates than previously used techniques.     

Tax reform,population ageing and the changing labour supply behaviour of married women

The burden of financing retirement incomes in an ageing population is predicted to rise sharply in future decades. This paper investigates the effects of reforms to the Australian tax-benefit system involving a greater reliance on proportional taxation for raising revenue and a more targeted welfare system for cutting government expenditure, in order to reduce expected budget deficits. Estimates of changes in net incomes and hours of work suggest that reforms of this kind shift the tax burden to lower and middle income households with a second earner and that they can have counter-productive labour supply effects. The study explores the impact of projected increases in female work force participation and illustrates the importance of shifts in the labour supply of married women in predicting the fiscal effects of demographic change.I wish to thank the discussants of this paper, Sijbren Cnossen and Hiromitsu Ishi, for their detailed and constructive comments which have been most helpful in revising the paper. Thanks are also due to John Buchanan, Glenn Jones, John McCallum and Elizabeth Savage for their comments and suggestions.This research has been supported by a grant from the Australian Research Council.     

Age-Specific Variation in Adult Mortality Rates in Developed Countries

This paper investigates historical changes in both single-year-of-age adult mortality rates and variation of the single-year mortality rates around expected values within age intervals over the past two centuries in 15 developed countries. We apply an integrated hierarchical age-period-cohort—variance function regression model to data from the human mortality database. We find increasing variation of the single-year rates within broader age intervals over the life course for all countries, but the increasing variation slows down at age 90 and then increases again after age 100 for some countries; the variation significantly declined across cohorts born after the early 20th century; and the variation continuously declined over much of the last two centuries but has substantially increased since 1980. Our further analysis finds the recent increases in mortality variation are not due to increasing proportions of older adults in the population, trends in mortality rates, or disproportionate delays in deaths from degenerative and man-made diseases, but rather due to increasing variations in young and middle-age adults.     

Women Left Behind? Poverty and Headship in Africa

Two stylized facts about poverty in Africa motivate this article: female-headed households tend to be poorer, and poverty has been falling in the aggregate since the 1990s. These facts raise two questions. First, how have female-headed households fared? Second, what role have they played in Africa’s impressive recent aggregate growth and poverty reduction? Using data covering the entire region, we reexamine the current prevalence and characteristics of female-headed households and ask whether their prevalence has been rising, what factors have been associated with such changes since the mid-1990s, and whether poverty has fallen equiproportionately for male- and female-headed households. Lower female headship is associated with higher gross domestic product. However, other subtle transformations occurring across Africa—changes in marriage behavior, family formation, health, and education—are positively related to female headship, resulting in a growing share of female-headed households. This shift has been happening alongside declining aggregate poverty incidence. However, rather than being left behind, female-headed households have generally seen faster poverty reduction. As a whole, this group has contributed substantially to the reduction in poverty despite their smaller share in the population.     

components of change in the number of households: 1970–1980

There was an increase from 62.8 to 79.1 million households in the United States during the 1970s. The number of households increased much more rapidly than the population. This paper decomposes this growth in the number of households into components associated with changing age and marital status composition and changing age by marital status-specific propensities to form households. About one-third of the increase in the number of households was due to increased age by marital status propensity to form households, and two-thirds was due to shifts in the age by marital status distribution and population growth. The increased propensity to form households had its major impact at ages under 35, and primarily among never-married persons. The composition component had its primary impact at ages 25–44 as a result of the baby boom, and also because of the increased fractions never married and separated and divorced.     

Changing families and changing mobility: Their impact on the central city

Urban scholars and planners look to evidence of recent gains in the number of nontraditional households as a potential source of increase to the population sizes and tax bases of declining central cities. While it is now well established that substantial gains in the numbers of small, nontraditional households have occurred since the 1950s, it has not been demonstrated that: (a) these households are more likely to relocate in the city than traditional family households (husband-wife with children under 18); or (b) their cityward relocation patterns will significantly alter trends toward smaller city household populations. This paper addresses these questions by examining changes in city-suburb migration stream rates by household type over periods 1955–60, 1965–70 and 1970–75 for large metropolitan areas, and assesses their implications for potential changes in the aggregate sizes of city household populations.
