Population over time
3 figuresRound Rock grew from 628 to 119,468 between 1880 and 2020. These are the recorded population figures Wikidata holds for this place, reached through the Geographic Names Information System number this page is keyed on rather than by name, so they belong to this place and not to another of the same name. Most are census counts, but not all are: an early figure may be a founding or settlement estimate, and an estimate published within five years of a census is left out. The change column is computed, and is left blank where more than 20 years separate a figure from the one before it, because a gap that long is not a change between two counts.

| March 2022 | Tornado (EF2) | Round Rock | - | The Round Rock - Granger tornado was a long-lived tornado that started approximately 1.25 miles southwest of the I-35/Hwy 45 interchange. The tornado tracked to that interchange moving into Williamson County and then moved northeastward across the county and into Bell County approximately 0.8 miles east of CR 352. Touchdown was found near the Silverstone subdivision where some shingles were torn off roofs and fences blown down. This was rated weak EF0 damage. The tornado quickly strengthened to EF1 as it continued to cross a residential area and business park where a section of roof was lifted off a warehouse building and several empty semi-trailers were tipped over. Several trees were snapped and air conditioning units were blown off the roofs of several buildings. The tornado crossed the I-35/Hwy 45 intersection and entered a large retail shopping center where roof and window damage was observed on several businesses. Still an EF1, the tornado crossed Dell Way and entered the Windy Terrace and Greenlawn Place neighborhoods. Widespread tree and roof damage was observed to multiple homes, a few lost their entire roof indicating the tornado had strengthened briefly to EF2. The tornado likely weakened a bit before regaining EF2 strength as it moved northeast and crossed Gattis School Rd. where substantial roof damage was seen on some homes near the intersection of Gattis School Rd. and windy Park Dr. The Clay Madsen Recreation Center and the adjacent playing fields sustained damage as well. The storm crossed A.W.Grimes Blvd. and entered the South Creek neighborhood where tree and roof damage was once again observed across many streets until it exited the neighborhood at Brushy Creek. Before crossing Hwy 79 the tornado made a slight right turn and started to parallel the south side of Hwy 79 and moved through the parking lot of the Kalahari Resort where multiple vehicles were damaged, trees blown down, and some windows of the resort were broken from flying debris. The tornado was likely at high end EF1 strength when it followed Brushy Creek into the Forest Bluff neighborhood off Red Bud Ln. Trees were blown down along the creek and several homes sustained roof damage where large sections of roof were blown off the house. The tornado crossed Red Bud Ln. and damaged a few businesses at the Red Bud Ln. and CR123 intersection. Shortly after crossing Hwy 79 east of Red Bud Ln., the tornado produced EF1 damage to an industrial park complex to numerous metal warehouse buildings. The tornado then weakened and continued to the northeast for nearly 5 miles producing minor EF0 damage to residential roofs, trees, and signs. Just east of FM1660, several homes under construction with only visible studs collapsed. As the tornado approached Chandler Rd. near the intersection with CR 101, the intensity of the tornado increased again with EF1 damage observed to a large metal building system with sections of the roof peeled away. Additional EF1 damage was observed to a stable on a property near the San Gabriel River with substantial tree damage as well. As the tornado neared CR337, EF2 damage was observed to a home on piers as the roof, most exterior walls, and some interior walls failed and were moved away from the property. As the tornado crossed Hwy 95 and CR345 EF1 damage was found on more homes and metal system buildings. Significant EF2 damage occurred to a home near the intersection of CR347 and CR346. The tornado then produced EF1 damage to trees, power poles, and a few structures as it crossed CR348, FM971, CR352, and CR357 before exiting Williamson County and entering Bell County. The maximum width of the tornado and its damage path was roughly 500 yards with maximum winds at 135 mph, the high end of EF2. Most of the 29-mile-long track however was at EF1 strength. There were reports of a total of 16 injuries, most of which were minor. There were no reported fatalities with this tornado. |
