What it’s like
The place. Sunnyvale is a town in Dallas County where nearly all homes are lived in by their owners, and where households earn far more than the county's typical household. Residents are somewhat older than in most places, a large share hold a four-year degree, and fewer people live below the poverty line than across the county as a whole. Homes here are valued well above what is typical for the country.
Work. Residents work mostly in schools, hospitals and social care, in professional and business services, in banks, insurance and property, and in shops. Within the town itself, Sunnyvale ISD, Baylor Scott and White Medical Center at Sunnyvale and FedEx Freight are among the largest workplaces. Commutes are on the long side, and a fair number of people work from home. Across Dallas County, jobs have grown only slightly over the past year.
Things to do. Lake Ray Hubbard, a reservoir, is a short drive away. The Dallas Museum of Art and the George W. Bush Presidential Center are both museums a longer drive away, and the Cotton Bowl, a stadium, is also a longer drive off. Winters are mild, summers are hot, and snow is rare, so getting out is easy in most months.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Sunnyvale’s census tracts, against the rest of the country; all of them together, relatively moderate. It is meant for planning, not a substitute for a local risk assessment or a flood map: FEMA’s index.
From the U.S. Census Bureau’s 2020 census and its American Community Survey (2020–2024 five-year estimates), and the Bureau of Labor Statistics. A survey, so each figure has a margin of error, and figures it is not sure of are left out. More on Dallas County and the Dallas-Fort Worth-Arlington, TX metro.
