2010 Census: Centenarians

"The 2010 Census counted 53,364 people age 100 and older in the United States, and they were overwhelmingly female. For every 100 centenarian women, there were only 20.7 centenarian men.

These figures come from a special report released today based on the 2010 Census that provides a portrait of the centenarian population in the United States describing their age, sex, race, Hispanic origin and living arrangement characteristics. The report, Centenarians: 2010, also compares centenarians with other age groups in the older population..

Small Area Income & Poverty Estimates (SAIPE) for School Districts, Counties, and States

"The U.S. Census Bureau, with support from other Federal agencies, created the Small Area Income and Poverty Estimates (SAIPE) program to provide more current estimates of selected income and poverty statistics than those from the most recent decennial census.

Estimates are produced for school districts, counties, and states. The main objective of this program is to provide updated estimates of income and poverty statistics for the administration of federal programs and the allocation of federal funds to local jurisdictions.  Estimates for 2011 were released in December 2012. These estimates combine data from administrative records, postcensal population estimates, and the decennial census with direct estimates from the American Community Survey to provide consistent and reliable single-year estimates..:
