Along with Hays and Kendall Counties, Comal was listed in 2017 of the nation's 10 fastest-growing large counties with a population of at least 10,000. In 2017, Comal County was second on the list; it grew by 5,675 newcomers, or 4.4% from 2015 to 2016. Kendall County was the second-fastest growing county in the nation in 2015 to 2016, growing by 5.16%. Hays County, third on the national list, had nearly 10,000 new residents during the year. As a result of this growth, the counties have experienced new home construction, traffic congestion, and greater demand for public services. Bexar County, which includes San Antonio, grew by 1.75% during the year, but its number of new residents exceeded 33,000.

Count Castell of the Adelsverein negotiated with the separate Darmstadt Society of Forty to colonize 200 families on the Fisher–Miller Land Grant territory in Texas. In return, they were to receive $12,000 in money, livestock, and equipment, and provisions for a year. After the first year, the colonies were expected to support themselves. The colonies attempted were Castell, Leiningen, Bettina, Schoenburg, and Meerholz in Llano County; Darmstädler Farm in Comal County; and Tusculum in Kendall County. Of these, only Castell survives. The colonies failed after the Adelsverein funding expired, and also due to conflict of structure and authorities. Some members moved to other Adelsverein settlements in Texas. Others moved elsewhere, or returned to Germany.

According to the U.S. Census Bureau, the county has a total area of 575 square miles (1,490 km²), of which 15 sq mi (39 km²) (2.7%) are covered by water.
