The Census Bureau report Parental Mortality is Linked to a Variety of Socio-economic and Demographic Factors by Zachary Scherer (5/6/19) provides charts of deceased parent(s) by sex, race (chart copied here), and socio-economic status.
For example, among those ages 45 to 49, 26% have lost their mother, while 45% have lost their father. Along these same lines, 7 in 10 of those ages 60 to 64 have a deceased mother, while about 87% have lost their father.
For example, among those ages 35 to 44, 43% of those living below the FPL have lost one or both parents, compared to 28% for those living in households with an income-to-poverty ratio of at least 400% of the FPL.
Parental loss, which varies by race and socio-economic status, is often accompanied by psychological and material consequences. These statistics demonstrate the way these new SIPP data can help assess how socio-economic and demographic characteristics are associated with parental mortality in the United States.
There are two other charts and a link to the SIPP data source.
