Advanced Education and Mortality Compression in the United States 147

sponsored by the National Institute of Aging (NIA) and conducted

by the University of Michigan. The HRS consists of six cohorts:

(1) Initial HRS cohort, born 1931 to 1941, first interviewed in 1992.

(2) AHEAD cohort, born before 1924, initially a separate study (The

Study of Assets and Health Dynamics among the Oldest Old), first

interviewed in 1993.

(3) Children of Depression (CODA) cohort, born 1924 to 1930, first

interviewed in 1998.

(4) War Baby (WB) cohort, born 1942 to 1947, first interviewed in

1998.

(5) Early Baby Boomer (EBB) cohort, born 1948 to 1953, first

interviewed in 2004.

(6) Mid Baby Boomer (MBB) cohort, born 1954 to 1959, first

interviewed in 2010.

The institutional population was not initially included in the

HRS sample at baseline interview, but the respondents are followed

into institutions, so institutional respondents are also included in the

current data. Since the HRS is a longitudinal survey, survival status

is available not only from National Death Index, but also obtained

during follow-up interviews. Overall, the HRS is representative of

the U.S. non-institutional population aged 51 years and older and

their spouses. This study makes use of HRS Rand file (version O,

1992-2012) with 37,317 observations, and the analytical sample is

age 50 and over (RAND Center for the Study of Aging, 2016).

Education

Education is reported in terms of years of formal schooling for

respondents. I distinguish older Americans’ educational attainment

into two sets of the categories: (1) 0-11 years, 12 years, and 13+

years; (2) 0-11 years, 12 years, 13-15 years, and 16+ years. The first

set of categories is consistent with the fitting form Montez et al.

(2012) and Brown et al. (2012). The second set of categories is the
