Immigrant Incorporation and Political Participation in the United States1

This article examines several factors related to immigrant incorporation that have been ignored in previous studies of voting participation. We add various immigrant‐related variables to a model that controls for individual resources, social incorporation, institutional barriers and contexts of political mobilization. We find little support for straight‐line assimilationist theories of immigrant adaptation. We also find that coming from a repressive regime has no significant effect on voting and that living in areas with Spanish‐language ballots does not increase the likelihood of voting among first generation Latinos. Our results also suggest that antiimmigrant legislation has a positive effect on participation among first and second generation immigrants. Overall, the immigrant‐related variables introduced in our analysis add significantly to the existing theoretical knowledge on voting participation in the United States.     

“Replacement Migration” from the Perspective of Equilibrium Stationary Populations

An equilibrium stationary population results whenever a population is projected assuming (constant) below-replacement fertility and annual flow of net migrants whose age-sex composition is also fixed. This framework is useful in interpreting the results in the U.N.'s report on Replacement Migration. It is especially helpful in seeing why the annual volume of immigration must accelerate if the policy goal is to maintain today's relatively youthful age structures. Replacement Migration is largely demographic in nature and ignores a number of potential connections to economics and other social sciences. Had those connections been strengthened, readers might have been more convinced that population aging and population decline are important problems that require immigration as a solution.     

An analysis of public opinion toward undocumented immigration

Public opinion toward illegal migration to the United States varies considerably across different segments of the population, but little is known about why some individuals hold more liberal attitudes than others. Several hypotheses are scattered throughout the research literature, but they have not been brought together in one place and tested using a common data set. Nor have the limited tests been satisfactory from a methodological standpoint. Instead of using multiple regression, typically analysts have relied on cross-tabulations of the data. This paper tests five hypotheses about attitudes toward illegal immigration and undocumented migrants using public opinion data from southern California. Only weak support is found for a labor market competition hypothesis. There is firmer evidence for hypotheses relating to cultural affinity between respondents and undocumented migrants and to the role of education. Respondents' evaluations of tangible costs and benefits to themselves also influence their assessments of illegal immigration. Finally, the results of this analysis provide additional support for a symbolic politics model of opinion formation when the model is extended to the issue of undocumented migration to the United States.     

Compensating changes in fertility and mortality

This paper illustrates a method of studying changes in vital rate schedules which have no effect on the intrinsic rate of population growth. These changes are described as compensating changes in fertility and mortality. The analysis proceeds from the discrete perspective of Leslie matrices, wherein the central idea is to establish the set of all compensating changes by identifying that class of Leslie matrices which possess the same positive eigenvalue, λ₁. A root-squaring technique is adapted for the purpose of estimating λ₁. Finally, a variety of compensating fertility and mortality changes is illustrated using data from Japan.     

Foreign and undocumented workers in California agriculture

In November 1986, the United States Congress passed the most sweeping reform of federal immigration laws in more than two decades. The major objective of the Immigration Reform and Control Act of 1986 is to curtail the flow of illegal immigrants into the United States. But the Act contains controversial provisions to assure agricultural producers who rely most heavily on illegal immigrants to harvest perishable crops that they will not suffer unfairly from changes in U.S. immigration laws. These special provisions for agriculture rest on two assumptions that heretofore have received little attention from researchers: (1) that agriculture now relies heavily on undocumented workers to harvest perishable crops, and (2) that growers hire undocumented labor because legal farmworkers are not available to work at wages growers can afford to pay. This paper presents preliminary findings from a study of the role of undocumented workers in California agriculture. The findings cast some doubt on the assumptions that undocumented workers are employed mostly in harvesting perishable crops and that growers hire illegal aliens because legal workers are not available. The analysis focuses on California because one-half of all undocumented immigrants in the United States are believed to live in this state.     

The Surprising Global Variation in Replacement Fertility

It is frequently assumed by the general public and alsoby some population experts that the value ofreplacement-level fertility is everywhere an averageof 2.1 lifetime births per woman. Nothing could befurther from the truth. The global variation inreplacement fertility is substantial, ranging by almost1.4 live births from less than 2.1 to nearly 3.5. Thisrange is due almost entirely to cross-country differencesin mortality, concentrated in the less developed world.Policy makers need to be sensitive to own-countryreplacement rates. Failure to do so could result infertility levels that are below replacement and lead tolong-run population decline. For example, the currentreplacement total fertility rate for the East Africa regionis 2.94. Lowering fertility to 2.10 would, under currentmortality conditions, result in a regional birthrate 29 percentbelow replacement.     

Immigration's prism: Historical continuities in the Kennedy-Simpson legal immigration reform bill

National debates about U.S. immigration policy usually involve a blend of three issues: (1) How many immigrants should the United States accept? (2) Where should the immigrants come from? and (3) What criteria should be used in selecting immigrants? The debate and compromise surrounding the Kennedy-Simpson bill, passed by the U.S. Senate in July 1989 and constituting the Senate's latest attempt to reform U.S.legal immigration policy, is no exception. This paper examines the evolution of the Kennedy-Simpson bill, partly to reveal current directions in U.S. immigration policy but more importantly to use this analysis as a prism through which historical continuities in U.S. immigration reforms may be isolated and evaluated.     

On Nonstable and Stable Population Momentum

This article decomposes total population momentum into two constituent and multiplicative parts: “nonstable” momentum and “stable” momentum. Nonstable momentum depends on deviations between a population’s current age distribution and its implied stable age distribution. Stable momentum is a function of deviations between a population’s implied stable and stationary age distributions. In general, the factorization of total momentum into the product of nonstable and stable momentum is a very good approximation. The factorization is exact, however, when the current age distribution is stable or when observed fertility is already at replacement. We provide numerical illustrations by calculating nonstable, stable, and total momentum for 176 countries, the world, and its major regions. In short, the article brings together disparate strands of the population momentum literature and shows how the various kinds of momentum fit together into a single unifying framework.
