Union County's economy is dominated by the state-corrections system — the Reception and Medical Center and other prison facilities are among the largest employers — alongside agriculture, county-and-school-district government, and residents commuting to Gainesville and Jacksonville. It is the smallest county in the state by land area and one of the most affordable.

The Union County School District is a very small, community-centered district serving Lake Butler and Raiford.

Union County has about 15,551 residents. On a net domestic basis it gained roughly 68 people and a net +$2.39M in adjusted gross income in the latest IRS filing year (county-to-county moves within the U.S.; this does not count international migration or births). Migration is the demand engine behind prices: when more income flows in than out, it supports both rents and values.

Expect Union to stay a very affordable, steady rural market over the next 12 months, anchored by corrections employment and its position between two job markets, with limited inventory and slow price movement.

Union County is small-town rural Florida at its most compact: the fishing and recreation of Lake Butler, the Santa Fe River at Worthington Springs, and a quiet, agricultural, tight-knit community midway between Gainesville and Jacksonville. It offers very affordable homes and land with a genuine small-town pace.

Union County's risks are rural: an economy heavily concentrated in corrections and agriculture, modest incomes, very limited services in the state's smallest county, and inland hurricane wind-and-rain exposure. It is inland, so surge is not a factor, and insurance is moderate. The market is very small.
