Demographics
Bexar County is one of Texas's fastest-growing metro counties
Bexar County had about 2,009,324 residents as of the 2020 Census and has continued growing, making it the fourth most populous county in Texas.
Bexar County has grown a lot over recent decades. People have moved in, and the resident base is young and growing. The county is home to San Antonio, one of the largest cities in the United States. The 2020 Census counted 2,009,324 people in Bexar County—a rise of about 17% from 2010. The county ranks fourth most populous in Texas.
San Antonio's military presence adds to the economy and population. Joint Base San Antonio combines Lackland, Randolph, and Fort Sam Houston. Healthcare, tourism, and manufacturing also fuel growth. The metro area keeps drawing new residents from other states and from within Texas.
Growth has put pressure on water, roads, and flood management. Many practical issues covered in these notes—from aquifer drought stages to new flood maps to expanding MUD districts—are direct results of this growth.
