Westfield had 30,068 residents at the 2010 Census. The 2025 estimate is 66,258. That is the fastest growth of any city in Indiana, and by the Census Bureau's count, the sixth-fastest in the country. Cities that grow this fast usually become sprawl. Westfield made two decisions that changed the outcome.
Grand Park
The first was Grand Park, a 400-acre sports campus on the city's north side with 31 multipurpose fields and 26 baseball and softball diamonds. It draws millions of visitors a year for tournaments, and it did something subtler for residents: it gave the city a reason to build the roads, hotels and restaurants that a town of 30,000 would never have justified, ahead of the people who would use them.
Grand Junction
The second was a downtown. Grand Junction Plaza, a 7.8-acre park and plaza on a remediated site at the center of the old town, opened as the civic heart the city had never had, with a creek, an amphitheater, a playground and the winter and summer event calendar that goes with them. The buildings around it followed. For a family choosing Westfield, the plaza is the difference between a subdivision and a place.

Four in five Westfield homes are owner-occupied, a quarter of residents are children, and the median household earns $122,789. Westfield Washington Schools serves about 9,700 students across ten schools and is among the higher-rated districts in the state. This is a young, family, homeowner city, and the housing stock reflects it: most of Westfield was built in the last twenty years.
What did Westfield homes sell for in July 2026?
In Westfield Washington Township, the July 2026 median sale price was $532,500, up 10.1 percent year over year, with 12 days from list to under contract and sellers receiving 98 percent of asking. Twelve days is the fastest on the Indianapolis to Greater Lafayette corridor, and a double-digit annual gain in a market with 274 homes listed on an average day is demand, not scarcity.
What it means
Westfield is where the corridor's growth is happening right now, and the market prices it that way. For a buyer, the new-construction share of the market means real choice and real competition among builders. For a seller, a resale home in an established Westfield neighborhood competes against new product every week, and wins when it offers what new construction cannot: mature trees, a finished basement, a known school assignment and a location closer to the plaza.
