HOME IMPROVEMENT A Lens on Small-Town America What is Micropolitan areas? For a lens on small-town America, turn to micropolitan statistical areas or “micros” for short. What’s a micro?

It’s a type of statistical area — first delineated by the U.S. Office of Management and Budget in 2003 — that provides more granular details of small population centers. Wyoming had the highest share of any state population living in micros — 44.2% — while Delaware, New Jersey and Rhode Island had zero micros.

Micros must contain a population concentration, or core, of at least 10,000 but less than 50,000, the threshold for metropolitan sta- tistical areas. They consist of a central county (or counties) plus any other coun- ties with strong commuting ties to it (or them). Taken together, these requirements typically translate into a small town and its surroundings. As of September 2018, there were 542 micros encompassing 660 counties in the United States. Some 27.2 million people 8.4% of the U.S. population – lived in these areas, according to 2017 Census estimates. The proportion of state populations living in micros varies considerably. Wyoming had the highest share of any state population living in micros — 44.2% — while Delaware, New Jersey and Rhode Island had zero micros. Massachusetts had one, accounting for less than 1% of its population in 2017. The growth rate of micros also varies from state to state. Between 2000 and 2017, seven states had micro populations that grew faster than their overall populations: Hawaii, Massachusetts, Michigan, Montana, North Dakota, Utah, and Wyoming. Utah’s micro population grew the fastest (43.6%) during that period. Twelve states experienced overall growth but saw losses in their micro populations: Connecticut, Illinois, Indiana, Iowa, Kansas, Mississippi, New York, Ohio, Pennsylvania, Vermont, Virginia, and West Virginia. The population of micros skewed older than that of the United States as a whole in 2017. Higher proportions of the population were ages 55 and older, and lower proportions were between ages 25 and 49. Micro areas were also less diverse than the nation as whole.
