Based on literally thousands of studies carried out over many decades, it is increasingly accepted that social and socioeconomic conditions act as important determinants of both individual health and the health of populations (Kaplan et al. 1987; Kaplan and Lynch 1997). Wages, income, and wealth, the nature of work, investments in human capital, and the levels of resources and risks in communities are now recognized by many, as arguably the most critical determinants of health (Kaplan 2001; Evans et al. 1994). It seems possible that social and economic policies in their ability to alter these determinants might also impact health, even though that is not their primary intent. Furthermore there is increasing recognition that historical and contemporary forces that differentially distribute these determinants to racial groups, within and across generations, may underlie many of the pernicious health gaps between racial groups that are found in the United States (Williams and Collins 1995).

ince 1920 the implicit and explicit urban model of growth in the United States has been that of concentric growth, the Chicago Model. Recently, this model of urban growth and change has come under attack by the Los Angeles school of urban studies, which postulates that urban growth is now much less patterned spatially and instead can be seen as nucleated and random. Based upon more recent growth patterns, it relies much more upon the experience of the West, including Los Angeles, but also Las Vegas and other cities. With the advent of data from the National Historical Geographical Information System (NHGIS), small area (census tract level) data on the development of about 60 urban areas now exist for the decennial censuses from 1940 to 2000, some 19 of these from 1930, and some 10 from 1920, and some limited information back to 1910 for eight of these cities. Using this newly available data this paper examines the actual pattern of urban growth in the United States from the early 20th Century to 2000. Though growth through 1940 was mainly outward as population increased, even then it was not completely uniform. From 1940 to 1970 growth largely continued outward, but with even less uniformity. Since 1970 growth is much less patterned. Both the concentric Chicago Model and the unpatterned Los Angeles school should give way to a more nuance and complex analysis of urban growth taking into account both the period and the place where growth or decline is occurring

Graphics are great for exploring data, but how can they be used for looking at the large datasets that are commonplace to-day? This book shows how to look at ways of visualizing large datasets, whether large in numbers of cases or large in numbers of variables or large in both. Data visualization is useful for data cleaning, exploring data, identifying trends and clusters, spotting local patterns, evaluating modeling output, and presenting results. It is essential for exploratory data analysis and data mining. Data analysts, statisticians, computer scientists-indeed anyone who has to explore a large dataset of their own-should benefit from reading this book.New approaches to graphics are needed to visualize the information in large datasets and most of the innovations described in this book are developments of standard graphics. There are considerable advantages in extending displays which are well-known and well-tried, both in understanding how best to make use of them in your work and in presenting results to others. It should also make the book readily accessible for readers who already have a little experience of drawing statistical graphics. All ideas are illustrated with displays from analyses of real datasets and the authors emphasize the importance of interpreting displays effectively. Graphics should be drawn to convey information and the book includes many insightful examples.

This article attempts to improve our understanding of the causal processes that contribute to intergenerational immobility by exploiting historical changes in compulsory schooling laws that affected the educational attainment of parents without affecting their innate abilities or endowments. We examine the influence of parental compulsory schooling on children's grade-for-age using the 1960, 1970, and 1980 U.S. censuses. Our estimates indicate that a 1-year increase in the education of either parent reduces the probability that a child repeats a grade by between 2 and 4 percentage points.

A large body of research has established a positive connection between an industry's productivity and the magnitude of its presence within locally defined geographic areas. This paper examines whether this relationship can be linked to a micro-level underpinning commonly associated with productivity: establishment scale. Looking at manufacturing industries across a sample of U.S. metropolitan areas, I find two primary results. First, average plant size increases substantially as an industry's employment in a metropolitan area rises. Second, the direct association between worker wages and local industry employment is more strongly associated with average plant size than the total number of plants, suggesting that localization economies may have significant organizational aspects.

In the decades following World War II, the center of gravity in American urban areas shifted from the inner city to the suburban ring.1 Suburbanization occurred along- side an influx of black migrants from the rural South, the majority of whom settled in downtown areas. My dissertation begins by assessing the causal relationship between this growing black urban population and white relocation to the suburbs. I then explore the motivation of households that left racially diverse cities. The existing historical literature on white flight emphasizes white distaste for living near black neighbors.3 However, because cities were already highly segregated by neighborhood, avoiding black neighbors did not require a suburban address. I focus instead on the civic costs of living in a diverse jurisdiction. These include compromising on public goods and sharing a single school system. Lastly, I consider the effect of black migration on the wages of similarly skilled workers in the northern labor market.

This paper studies the loss of human capital that emigration generates in the country of origin. To that end I estimate the human capital distribution of emigrants had they not migrated. Unlike previous studies, I take into account the selection of migrants in terms of unobserved characteristics that affect their productivity. Wages in Mexico of those migrants who come back home after being abroad for some time will be crucial to learn something about the selection of non-returning migrants in terms of unobserved productivity. To test whether returning migrants' wages contain any useful information, I follow two steps. First, I use the model of Borjas and Bratsberg (1986) to show that, regardless of the cause for coming back, the distribution of abilities of non-returning migrants is more similar to the distribution of temporary migrants than to that of non-migrants. Moreover, I test some implications of the model in the data. Second, I show that returning migrants' wages reflect their pre-emigration productivity and are not affected by possible human capital gains derived from the decision to emigrate. Taking into account all this evidence, I use returning migrants' wages in Mexico upon return to estimate the distribution of human capital of non-returning migrants had they not migrated. I show that emigrants come form the middle part of the distribution of human capital in the origin country. I find evidence that taking unobserved human capital factors into account is relevant for the dispersion of the estimated distribution as well as for each of its quantiles. Moreover, it does not greatly affect the aggregate mean of human capital.

Growth of human capital, defined as the change in the fraction of a metropolitan area's labor force with a bachelor's degree, is typically viewed as generating a number of desirable outcomes, including economic growth. Yet, in spite of its importance, few empirical studies have explored why some economies accumulate more human capital than others. This paper attempts to do so using a sample of more than 200 metropolitan areas in the United States over the years 1980, 1990, and 2000. The results reveal two consistently significant correlates of human capital growth: population and the existing stock of college-educated labor. Given that population growth and human capital growth are both positively associated with education, these results suggest that the geographic distributions of population and human capital should have become more concentrated in recent decades. That is, larger, more-educated metropolitan areas should have exhibited the fastest rates of increase in both population and education and thus "pulled away" from smaller, less-educated metropolitan areas. The evidence largely supports this conclusion.

I use a new data set of households linked between the 1860 and 1870 censuses to study frontier migration. Households that moved to the frontier to farm were more likely than non-migrants to have been poor, landless, and illiterate, and to have had young children. Also, after controlling for observable differences, migrants had below average abilities to accumulate wealth. These findings suggest fewer opportunities for migrants to accumulate wealth in non-frontier areas and a reason for their migration. Nonetheless, migrants fared well, accumulating wealth at high rates. The gains in wealth of migrants, especially those with long tenure on the frontier, suggest the extraordinary benefits of migration. (c) 2005 Elsevier Inc. All rights reserved.

Sometime around the year 1800, if not before, couples throughout New England began talking to each other about the desirability of postponing children. Why they did so is something of a mystery, but the consequences of those conversations are unmistakable: The median size of completed families in the region halved for cohorts marrying between 1790 and 1840. The number of children per family fell in the rural interior as well as in crowded coastal communities. How couples in the period actually managed to control family size is also a mystery, because no magic pills or rubber condoms were then available. No one at the time even understood the physiology of human reproduction. People obtained their health information from gossip or folklore, and women shared recipes for herbal remedies. The timing of ovulation was utterly unknown even to university trained doctors. Any rhythm method was necessarily based on false assumptions and any success with it based on luck. The only contraceptive barriers available in the early decades of the nineteenth century were clumsy sheaths made of animal organs used by city prostitutes and their customers. Their unsavory connotations aroused disgust and revulsion among the respectable few who knew about them, yet no acceptable alternatives existed.

If you are an entrepreneur with a plan, you are a person to be respected! You are ready to answer that age-old question, "Are you ready to be an entrepreneur?" with a resounding "yes". You are prepared with the most important, fundamental tool for your personal and business success: a sound, convincing and practical business plan.We all dream one day to be our own boss, to enjoy the benefits of business ownership, to garner the respect and admiration of our friends and colleagues as someone who "has made it." The key step from moving out of a faceless cube to striking a pose of independence and self-worth is a solid business concept, articulated through a business plan where no stone is left unturned.See yourself with a promising business idea? Now it is time to take the first step to put that plan into action that means crafting a business plan so convincing and so complete that it will attract the immediate attention of investors and key employees.

Discrimination in womens wages is a much studied topic; various attempts have been made to measure the effect of the Federal Equal Pay Act of 1963 on the difference between men and womens wages. Generally these studies find little positive effect and sometimes a negative effect on womens relative wages. Previous studies had no control group and didnt take into account the fact that some states passed equal pay legislation before the federal law. By using the states as a control group I find that the federal law had a significant positive impact on womens wages and labor force participation.

This chapter addresses the intersection of these two domains of rapidly changing demographic behavior. Specifically, we analyze the family patterns of Hispanics, focusing on several key issues. First, to place the present in a larger context, we document trends in several indicators of family change. Comparisons between Hispanic subgroups, non-Hispanic whites, and non-Hispanic blacks provide information on the extent to which Hispanics have shared in the general shifts in family configurations that took place during the past several decades. This issue is fundamental to understanding the nature of family life among Hispanics as well as links between changing family processes and family members' access to social and economic resources. As noted by Vega (1995, p. 6), Changing family structures, including marital disruption and cohabitation, could represent the most important issue for Latino family theory and research in the decade ahead.

Foreign-born workers do not substitute perfectly for, and therefore do not compete with, most native-born workers. Rather, the complementary nature of the skills, occupations, and abilities of foreign-born workers increases the productivity of natives, stimulates investment, and enhances the choices available to consumers. As a result, immigration increases the average wages of all native-born workers, except those who do not have a high-school diploma. Even for the small and shrinking number of native-born workers without a high-school diploma, the decline in wages from immigration is much smaller than some have estimated. A well-balanced immigration policy that attracts foreign-born workers at both ends of the educational spectrum would maximize the economic benefits of immigration for the native-born and build on the traditional appeal of the United States as a country of destination for both highly skilled and less-skilled immigrants
