Start with the geography your site must serve
Mason City is recorded as a municipality in Cerro Gordo County, Iowa. The 2020–2024 American Community Survey 5-year population estimate for Mason City city is 27,050, with a margin of error of 27. That figure describes the municipality; it does not establish search demand, legal need, competition, leads or revenue. For hosting, its practical value is narrower: it helps you define the geographic scope of the site and the audience whose experience you will evaluate. A Mason City law firm may also serve people elsewhere in Cerro Gordo County or Iowa, but those relationships should be specified by the firm rather than assumed from the city record.
Recommended approach
List the locations, service pages, contact paths and audiences that the site is actually intended to support. Use that inventory when testing page speed, redirects, forms and analytics after any hosting change. Do not use the population estimate as a forecast of website traffic.
