Just how many people live in Marble Falls?

The exact population of Marble Falls is hard to pin down without a more recent U.S. Census count, but city staff believe it could be as high as 9,783, based on the number of new homes and apartments. That guess could be a bit high, but it is more accurate than the “6,077” currently on Marble Falls city limit signs.
Marble Falls Development Services issued a report in October 2024 estimating the city’s population to be about 8,395, which was around 13 percent more than the U.S. Census’ 2022 estimate of 7,423.
The 9,783 estimate reported during a Marble Falls City Council meeting April 15 is 29.18 percent higher than the U.S. Census’ 2023 estimate of 7,573 and greater than Development Services’ 2027 population prediction of 9,578.
The next official U.S. Census count is scheduled for 2030. The last one was done in 2020, during the COVID-19 pandemic.
Development Services Director Scarlett Moreno explained that the department’s estimates are based on a formula that uses the number of available multi-family housing units and single-family housing units and a household occupancy of 2.34 people. Development Services skews the numbers, estimating 70 percent total occupancy for multi-family housing and 90 percent for single-family housing.
“We recognize that this approach can lead to overestimation, especially when new multi-family developments are not yet fully occupied,” she told DailyTrib.com. “We are actively working on a long-term solution to improve the accuracy of our estimates moving forward.”
While the exact number of Marble Falls residents is difficult to determine, the number of new residences is not. Exactly 822 multi-family units and 155 single-family units have come online since October 2024. This can be attributed to the completion of multi-family projects at Thunder Rock Prose, ParcHaus, and Flatz 281.
More housing is on the way, including 164 multi-family units already permitted and 675 in review from other developments.
“The recent population growth that we’ve seen in Marble Falls illustrates just how much pent-up demand there has been for housing in our market,” said Marble Falls Economic Development Corp. Executive Director Christian Fletcher. “Now that we have a growing supply of new single-family homes and apartments, we should be able to better accommodate the needs of our workforce.”
