As the baby boom cohorts expand the number of U.S. retirees, population estimates of the employment, withdrawal and reentry behaviors of older Americans' remain scarce. How long do people work? How frequently is retirement reversed? How many years are people retired? What is the modal age of retirement? And, how do the patterns for women compare to those for men? Using the 1992-2004 Health and ...

BACKGROUND Information is lacking on the impact of visual impairment on the quality of life of elderly Africans. This study aims to examine the impact of self-reported visual impairment on the quality life of an elderly Nigerian sample. RESULTS Four hundred and fifty-three (22.3%) of the respondents reported impairment for distant vision, 377 (18.4%) reported near vision, and 312 (15.2) repor...

The multistate life table (MSLT) model is an important demographic method to document life cycle processes. In this paper, we present the SPACE (Stochastic Population Analysis for Complex Events) program to estimate MSLT functions and their sampling variability. It has several advantages over other programs, including the use of micro-simulation and the bootstrap method to estimate the variance...

OBJECTIVES To investigate the robust education-health association found in Western developed nations in the Japanese context. We examined disability and mortality transitions and computed active life expectancy (ALE) by educational attainment for a cohort of Japanese adults aged 65+ years. METHOD Nationally representative data from the Nihon University Japanese Longitudinal Study of Aging ove...

BACKGROUND: Socioeconomic and ethnic inequalities in health are of great concern, and life expectancy provides a readily understood means of monitoring such inequalities. The objectives of this study are to (1) measure life expectancy by socioeconomic deprivation and ethnicity, and (2) describe trends in the deprivation gradient in life expectancy since the mid-1990s. METHODS: Three years of na...

Project Summary Current mining technology typically applies to centrally stored data (i.e., in one single repository, with central administration etc.). However, real-life datasets are often decentralized (i.e., consisting of several tables, perhaps obtained via normalization or partitioning / allocation, stored in several repositories). The goal of this research project is to develop mining te...
