While the influx of people from other countries and other parts of the country is adding to San Antonio's growth, the city is also experiencing healthy natural growth with a high birth rate and a low death rate. The overall ten-year growth pattern is showing absolutely no signs of slowing down for the upcoming 2020 population census in the United States.

With Texas as a whole experiencing such a population boom, it may be the most populous state, surpassing California, by 2030. While it won't exceed Dallas any time soon, San Antonio's growth will allow it to maintain its spot as the second most populous city in Texas for the time being.

The Payaya Indians originally inhabited the San Antonio River Valley. A group of Spanish missionaries and explorers discovered the area on 1691 on June 13, the feast day of St. Anthony, and named the river and site "San Antonio" in his honor.

The early San Antonio settlement, as well as San Antonio de Valero Mission (now the Alamo) began as a way to reassert Spain's dominance over Texas from the French in Louisiana. The Alamo and nearby sites were constructed with the help of the Payaya Indians. In 1719, 400 families were transported from the Canary Islands, Havana and Galicia to populate the new province. By 1730, 25 families had made it to Cuba, and ten were sent to Veracruz on the way to San Antonio.

Over some time, the city became the largest Spanish settlement in the state, and it was the site of the famous Battle of the Alamo in 1836, in which outnumbered Texian forces were defeated, and the Alamo defenders were killed.

The decision to annex Texas and allow it to become a part of the Union in 1845 led to the Mexican-American War, which reduced San Antonio's population by 2/3 to just 800 people, although it grew to 15,000 by the time the Civil War began in 1860.

Since 1970, San Antonio's population has almost doubled from 650,000 to more than 1.2 million in 2005. This was caused by both population growth and land annexation.
