The Census Bureau groups data on households into census tracts,
where each census tract has a total population of about 4,000
residents. Census tracts should be divided so that the households
in the census tracts share certain characteristics, such as
economic status. Even though most tracts are around 4,000
residents, there is some variability, which is the focus of this
lab. In practice, census tracts usually have a population between
1,200 and 8,000 people.
