**Commuting Zone Life Expectancy**: Commuting zone (CZ)-level life expectancy estimates for men and women, by income quartile



**Commuting Zone Life Expectancy Trends**: CZ-level estimates of trends in life expectancy for men and women, by income quartile



**Commuting Zone Characteristics**: CZ-level characteristics



**Commuting Zone Life Expectancy for larger populations**: CZ-level life expectancy estimates for men and women, by income ventile


description: #Section 15  


This table reports life expectancy point estimates and standard errors for men and women at age 40 for each quartile of the national income distribution by state of residence and year. Both race-adjusted and unadjusted estimates are reported.

description: #Section 11  


This table reports US mortality rates by gender, age, year and household income percentile. Household incomes are measured two years prior to the mortality rate for mortality rates at ages 40-63, and at age 61 for mortality rates at ages 64-76. The “lag” variable indicates the number of years between measurement of income and mortality.

Observations with 1 or 2 deaths have been masked: all mortality rates that reflect only 1 or 2 deaths have been recoded to reflect 3 deaths

description: #Section 3  


This table reports coefficients and standard errors from regressions of life expectancy estimates for men and women at age 40 for each quartile of the national income distribution on calendar year by commuting zone of residence. Only the slope coefficient, representing the average increase or decrease in life expectancy per year, is reported. Trend estimates for both race-adjusted and unadjusted life expectancies are reported. Estimates are reported for the 100 largest CZs (populations greater than 590,000) only.

This table reports US population and death counts by age, year, and sex from various sources. Counts labelled “dm1” are derived from the Social Security Administration Data Master 1 file. Counts labelled “irs” are derived from tax data. Counts labelled “cdc” are derived from NCHS life tables.

description: #Section 12  


This table reports numerous county characteristics, compiled from various sources. These characteristics are described in the county life expectancy table.



Two variables constructed by the Census Bureau that measure local government expenditures contained in this data set are set to zero for all counties in New York City other than New York County (Manhattan). This is due to the unique fact that New York City spans multiple counties, and that New York City governmental spending originates in a single county. The two affected variables are subcty\_exp\_pc and taxrate.
