The 2020 census may be three years away, but local government officials are already preparing for the gigantic task ahead. On Tuesday, a workshop was held to find out what the city needs to do to get ready.

"If we can get our elected officials, our city manager, our economic developers involved in the census participation, they can make sure everyone is accounted for," said Gloria Vasquez, the director of regional services for the Alamo Area Council of Governments.

That's why they're starting now. Vicki Mcintire, Assistant Regional Director of the U.S. Census Bureau said,

"So we can know where growth is, where the new housing units are being added, where condos are going up to make sure we identify all of the housing needs where people are living, particularly in fast growing cities like San Antonio," said Vicki Mcintire, the assistant regional director of the U.S. Census Bureau.

Its been seven years since the last census, and San Antonio has grown by well over 100,000 people since 2010. That makes counting heads a little more tricky.

"The growth we are experiencing makes it a little more difficult for us to count Texans because we have many new Texans here and many new housing units," said Dr. Lloyd Potter, a Texas state demographer and UTSA professor.

The U.S. Census Bureau uses many techniques to build address lists and find everybody, from data from the 2010 census, postal files, state and local government files, and even satellite imagery.

In a few years, if that census worker comes to your door because they don't have your information, its important you participate and get counted so Texas gets the representation it deserves in Congress, and San Antonio gets federal dollars.

"At the end of the day, if we do the census right, we get allocated dollars, federal dollars that come to needs in this great community that is growing so quickly," San Antonio Chamber of Commerce CEO Richard Perez said.

San Antonio is a community that is expected to double in size by 2040.
