​

Answer 1

Answer:

ERS researchers and others who analyze conditions in "rural" America most often study conditions in nonmetropolitan (nonmetro) areas, defined on the basis of counties. Counties are the standard building block for collecting economic data and for conducting research to track and explain regional population and economic trends. Nonmetro counties (see the map below) include some combination of:

open countryside,

rural towns (places with fewer than 2,500 people), and

urban areas with populations ranging from 2,500 to 49,999 that are not part of larger labor market areas (metropolitan areas).
