Columbus Authority

Also known as: Columbus Metro Authority

Columbus is a middle-income mid-sized city of 914,802.

Columbus is, by a considerable margin, the largest city in Ohio, and yet it carries the administrative designation of a municipality governed by a city charter — a distinction that turns out to matter quite a lot when you start reading the building codes. According to Census ACS 5-Year 2024 data, the city's total population stands at 914,802, which places it comfortably among the twenty largest cities in the United States, a fact that seems to surprise people who have not visited recently.

Demographics and Age Profile

The population skews notably young. According to Census ACS 5-Year 2024 data, the median age in Columbus is 33.2 years, and residents between 18 and 34 years old number 287,528 — a cohort large enough to constitute a meaningful share of civic and economic life. Children under 18 account for 201,218 residents, or roughly 22 percent of the total population. The Census ACS 5-Year 2023 data further describes a city of 386,581 total households, of which 200,236 are family households. The racial composition, per the same source, includes 482,843 white residents, 263,048 Black residents, 52,431 Asian residents, and 71,511 Hispanic or Latino residents.

Housing and Affordability

Housing affordability in Columbus occupies a middle position that economists sometimes describe as "moderate." Derived from Census income, housing, and poverty data, the home price-to-income ratio sits at 3.8 — meaning the median home costs roughly 3.8 times the median annual household income, which the Census ACS 5-Year 2023 data places at $65,327. Renters fare somewhat better in relative terms: rent as a percentage of income is 22.2 percent, a figure that falls within the range generally considered affordable by housing researchers. These numbers reflect a city that has grown rapidly but has not yet reached the acute affordability stress visible in coastal metros.

Building and Zoning Regulations

Columbus adopts its building standards by reference to state codes, a common Ohio practice that nonetheless produces a specific local legal architecture worth understanding. Per the Columbus Municipal Code at section 1311.01, the city has adopted the Ohio Building Code (OBC) as published in Division 4101:1 et seq. of the Ohio Administrative Code, pursuant to Ohio Revised Code § 731.231. The ordinance, passed as Ord. No. 2017-45 on September 19, 2017, incorporates the OBC "as if fully set out herein," with copies filed in the office of the Clerk of Council and available at the county law library. A parallel provision at section 1315.01 of the Municipal Code adopts the Residential Code of Ohio (RCO), published in Division 4101:8 et seq. of the Ohio Administrative Code, under the same statutory authority. The RCO adoption also includes Appendix G, a detail that matters for certain residential construction scenarios.

Variances and exceptions to these codes flow through the Board of Zoning and Building Appeals. Per section 9.4 of the Municipal Code, the Board is empowered to hear appeals from zoning and building ordinances and from orders of administrative officials, granting exceptions or variances only when "there are practical difficulties or unnecessary hardships in the way of carrying out the strict interpretation of said ordinances" and when doing so remains in harmony with the general purpose of the ordinances and the public health, safety, and general welfare.

Broadband Access

Broadband coverage in Columbus is, by the available federal data, essentially universal at standard thresholds. According to FCC Broadband Data Collection figures as of June 2025, 100 percent of the city's 454,335 housing units have access to service at 25/3 Mbps, 100/20 Mbps, and 250/25 Mbps. Access to gigabit-class service (1000/100 Mbps) reaches approximately 31.2 percent of units — a meaningful share, though well below full coverage, suggesting that the highest-tier infrastructure buildout remains incomplete across portions of the city.

Air Quality

Columbus air quality in 2024 was, on most days, unremarkable in the best sense. According to EPA AQI Annual Summary 2024 data, the city recorded 242 days with a measured Air Quality Index. Of those, 200 were classified as "good" and 41 as "moderate." One day fell into the "unhealthy for sensitive groups" category. Zero days were recorded as unhealthy, very unhealthy, or hazardous. The maximum AQI recorded during the year was 105, and the median AQI was 43 — a figure that sits comfortably in the good range.

Education

Columbus hosts a substantial higher education presence. According to NCES IPEDS 2022 data, 21 colleges and universities operate within the city. The most prominent is Ohio State University-Main Campus, which according to College Scorecard data enrolls 45,638 students, charges in-state tuition of $13,244 and out-of-state tuition of $40,022, carries an average SAT score of 1,387, admits approximately 60.6 percent of applicants, and reports a completion rate of 80 percent.

Civic and Community Infrastructure

The city supports a dense network of civic organizations. According to IRS Exempt Organizations data, Columbus is home to 584 churches and 20 arts organizations, among them Ballet Metropolitan Inc., Pro Musica Chamber Orchestra of Columbus, and the Ohio Art League. Thirty-eight civic service organizations operate in the city, including local affiliates of Habitat for Humanity International and Altrusa International Foundation. Five animal rescue and shelter organizations serve the area, including Columbus Pet Rescue and Operation Pet Rescue, per IRS Exempt Organizations data.

Childcare infrastructure is substantial: according to state licensing data, 398 childcare centers operate within Columbus, ranging from large center-based facilities to smaller community programs. The chamber of commerce presence is represented by the Chamber of Commerce Executives of Ohio, per IRS EO BMF records.

Climate

Columbus experiences a temperate continental climate. According to NOAA ACIS data drawn from the Columbus WCMH station, located approximately 3.5 miles from the city center, the average annual temperature is 54.2 degrees Fahrenheit and annual precipitation averages 47.0 inches. These figures describe a city with genuine seasons — winters cold enough to matter, summers warm enough to notice — without the extremes that characterize more northerly or southerly parts of the country.

Banking Access

Financial services infrastructure in Columbus includes branches of major national institutions. According to FDIC Institutions/Branches data, JPMorgan Chase Bank, National Association maintains a presence in the city, alongside First Federal Savings and Loan Association's Columbus Branch, located at 1050 Beecher Xing N.
