So, How Many People Use Twitter in San Antonio? According to the Census, 1,547,253 people live in San Antonio, Texas, 25% of which are under the age of 18. That leaves 1,160,439 adults. Pew Research shows that 22% of American adults use Twitter. It’s reasonable, then, to project that 255,296 adults in San Antonio use Twitter. Why Should I Care About Twitter Users? Twitter users are a different demographic. People who choose Twitter are slightly different than other social media users, according to Pew Research. They spend time on Twitter to read and engage. They’re learning, researching. They are looking to make connections. I have had the same experience managing client Twitter accounts since 2009. You don’t have to care about Twitter. But you should ask yourself if you care about that demographic. Can your business afford to not reach 250,000 people who are highly educated with a higher income than the US population at large? Can your San Antonio business afford to ignore the social media users who believe in true diversity and inclusion?
