Highlights of new research findings from the 1993 annual meeting of the Population Association of America are given for the following topics: immigration and birth rates of immigrants, longevity, environmental protection and girls education, demographic perspectives on world population growth, the demographic transition in Africa, China's fertility, AIDS in Africa, and residential segregation. A recent report by Los Angeles County showed that immigrants consumed considerable county government services, but California demographers found that recent immigrants also paid substantially more in federal, state, and local taxes. A New Jersey researcher found that for each 1% concentration of Puerto Rican born males, and not all immigrants, in New Jersey, there was a 4% decrease in average weekly wages of black men. A longevity study found that "successful aging factors" overlap rather than add up to contribute to good health among the very old. A Duke University researcher countered that there was a poor evidence of a natural limit to life; Americans over the age of 85 years may have the lowest mortality in the world.
