Exercise

Getting Census data with tidycensus

In this exercise, you will load and inspect data from the US Census and American Community Survey. The core functions of get_decennial() and get_acs() in tidycensus are used to obtain data from these sources; the Census and ACS are the defaults for these functions, respectively.

By inspecting the data, you'll get a sense of differences between decennial US Census data and data from the ACS, which is based on a sample and subject to a margin of error. Whereas get_decennial() returns a data value for each row, get_acs() returns estimate and moe columns representing the ACS estimate and margin of error.
