In September 2002, a technical working group met to resolve previously published inconsistencies across national surveys in trends in activity limitations among the older population. The 12-person panel prepared estimates from five national data sets and investigated methodological sources of the inconsistencies among the population aged 70 and older from(More)
This article uses the Asset and Health Dynamics Among the Oldest Old (AHEAD) study to examine the extent to which observed differences in the prevalence of chronic conditions and functional limitations between Black and White adults (aged 70+) in the United States can be attributed to differences in various aspects of socioeconomic status (SES) between(More)
BACKGROUND Although the general relations between race, socioeconomic status, and mortality in the United States are well known, specific patterns of excess mortality are not well understood. METHODS Using standard demographic techniques, we analyzed death certificates and census data and made sex-specific population-level estimates of the 1990 death(More)
We calculated population-level estimates of mortality, functional health, and active life expectancy for black and white adults living in a diverse set of 23 local areas in 1990, and nationwide. At age 16, life expectancy and active life expectancy vary across the local populations by as much as 28 and 25 years respectively. The relationship between(More)
OBJECTIVES This article used a new data source to examine the issue of disability trends among elderly persons and examined the potential implications of these trends on future health and long-term care needs. METHODS We used the 1992-1996 Medicare Current Beneficiary Survey to examine time trends in rates of activities of daily living and instrumental(More)
STUDY OBJECTIVE To describe variation in levels and causes of excess mortality and temporal mortality change among young and middle aged adults in a regionally diverse set of poor local populations in the USA. DESIGN Using standard demographic techniques, death certificate and census data were analysed to make sex specific population level estimates of(More)
The increase in undocumented immigration between 1999 and 2007 contributed to an increase in the number of uninsured people in the United States. During this period, the number of undocumented immigrants increased from an estimated 8.5 million to 11.8 million, leading to an estimated additional 1.8 million uninsured.

BACKGROUND Although geographic differences in Medicare spending are widely considered to be evidence of program inefficiency, policymakers need to understand how differences in beneficiaries' health and personal characteristics and specific geographic factors affect the amount of Medicare spending per beneficiary before formulating policies to reduce(More)
Health disparities among racial and ethnic groups have a long history and continue to exist in the United States. The U.S. government has established as a goal for the year 2010 the elimination of racial/ethnic health differences in six areas. This article examines disparities in one of those areas: access to high-quality health care. Several measures of(More)
Data from the National Health Interview Survey showed a trend toward worsening self-reported health among older American men and women during the 1970s. This evidence--combined with the significant declines in age-specific mortality observed since the 1960s--led some researchers to suggest that the health of the older population is declining. An examination(More)
