Summary This paper shows that the Indiana Amish, a high-fertility Anabaptist population, regulate their marital fertility according to their family finances. We linked demographic data from the Indiana Amish Directory with personal property tax records at 5, 15 and 25 years after marriage and found fertility differences by occupation and wealth. Correlations between family size and wealth at the beginning, middle and end of childbearing years were positive. Wealthier women exhibited higher marital fertility, had longer first birth intervals, were older at the birth of their last child, and had larger families than poorer women. Over the past 30 years, marital fertility has remained constant among older women; but birth rates among younger women have been rising rapidly.  相似文献

In President Carter's National Energy Plan, there are variable factors, including the coal production rate, standards for home insulation and auto mileage, various taxes, but not the population growth rate. The latter factor is considered to be beyond the influence of public policy; it is a constant. This seems irrational to zero population growth proponents, for there are alternatives to continued U.S. population growth, and these alternatives are more readily attainable than some of the elements in Carter's plan. With some national initiatives in population planning, energy use would be considerably less. Thus, the question remains - Why would Carter not deal with the population factor? 1 reason for this is the fact that population planning is a long-term approach; the results are indirect and not reflected immediately in energy comsumption. Yet, a start must be made in the short-term if there are ever to be long-term benefits. Russell Peterson has suggested that Carter could be ignoring the population factor because of "political sensitivity." Carter's people have ignored the population issue, and press coverage following Carter's energy pronouncements has excluded the population factor. In a situation such as this there seems little hope for increased public awareness of the population factor in energy or other public concerns.  相似文献

Recent patterns of Hispanic immigration to the United States are examined using data from the U.S. Immigration and Naturalization Service. "From 1960 to 1978 Hispanic immigration increased significantly, reflecting the general acceleration in total immigration to the United States. Demographic trends reveal that Hispanic immigrants are increasingly working-age women. Their occupation composition is primarily blue collar, with operatives emerging as the predominant job category during the 1970s." The authors note that these immigrants settle primarily in a small number of urban centers of Hispanic population and culture in the United States, and thus the effects of immigration will be concentrated on the low-skill segment of particular urban labor markets that already contain large numbers of Hispanic workers.  相似文献

"The basis of statistical tests of significance of association between fluoride level in drinking water and cancer death rates is discussed. Reference is made to two reported studies in each of which cancer death rates of a number of [U.S.] cities were used. It is argued that between city variation should be taken into account when performing tests of significance. In one of the two studies this was done informally; in the other between city variation was ignored."  相似文献

Because of the popularization of a responsible agricultural production system, the livilihood of peasants has been improving greatly, while the demands and needs of the general public are also increasing at the same time. Still under the influence of the traditional belief of carrying on one's family line and emphasis on having male children, married people prefer to have more childre, and the birth rate is now rising again. In order to solve this new problem, we need to teach the peasants national policies on population, land utilization, and food supply. In order to initiate a new situation in family planning work, we need to control this "gold key" of ideological education and propaganda. The emphasis should be placed on ideological education for cadres at all levels as well as the general public in order that they may understand the Party's strategy. Education on the national strategy should be combined with material interests of the peasants, and reward and punishment in production should also be linked up with that of family planning. Social measures are needed to reduce economic burdens of the peasants, offer better treatment for single-child households, and provide adequate care for old and retired people. Family planning projects should be consolidated and improved. Scientific management, facilities and techniques for birth control, compensation for working personnel in family planning, and other practical problems deserve immediate attention and solution.  相似文献

This paper reports the development of a self-administered Hebrew-language questionnaire for assessing patient satisfaction with primary care in Israel. Four scale measures of patient satisfaction were empirically constructed. These scales pertained to doctor conduct, doctor-patient communication, teamwork, and ease of access. In addition, a single direct question was used to measure overall satisfaction with the care. Ratings of all aspects of care were negatively skewed, with doctor-conduct and doctor-patient communication usually being the most satisfactory aspects and access the least satisfactory. It was shown that different practices, or the same practice at different points in time, can easily and meaningfully be compared, using mean satisfaction scores, measures of standard deviation, or percentages in each practice with ratings above (or below) the overall mean of all practices. The use of specific measures of patient satisfaction for comparison and intervention is discussed.  相似文献
