Estimates of population characteristics such as the population distributions by age, sex, marital status, race, and Hispanic origin follow a similar top-down bottom-up process. At the block group unit of analysis, the latest and best information from the Census Bureau’s American Community Survey (ACS) – the largest household survey in the US – is integrated with Census 2010 data to produce timely, accurate small-area estimates. Population characteristics are estimated using demographic estimation and projection models to achieve a preliminary set of estimates which are then reconciled to top-down estimates using iterative proportion fitting.
Population by Hispanic/Non-Hispanic data is provided as 4 data packages: Census 2010 (2k), Five-year (5y) projections, Census 2010 dataset (by) and Current year (cy) estimates dataset and include variables such as:
- Sex by Age (Hispanic or Latino)
- Sex by Age (Not Hispanic or Latino)
- Hispanic or Latino by Specific Origin
