censusapi is a lightweight package to get data from the U.S. Census Bureau's APIs. More than 1,500 API endpoints are available, including data from surveys such as the Decennial Census, American Community Survey, International Trade Datasets, Small Area Health Insurance Estimates and the Economics Indicators Time Series. getCensus() lets users retrieves data from any of those datasets using simple, consistent syntax.
The package also includes metadata functions to help users determine which datasets are available and the variable, geography, and other options in each of them.

- percent of households without an internet subscription (S2801_C02_019E)
- Census tract name

Users can pass any valid parameters to the APIs using getCensus(). The Census Bureau refers to these filterable parameter variables as "predicates".
Using the Small Area Health Insurance Estimates, we can use these predicates to get the uninsured rate (PCTUI_PT) for specific demographic groups, including income group, age group, and race/ethnicity.
