How to prepare and behave

This is editorial guidance, not information from the employer.

Know your rights as a candidate and an employee:

The city

The job is in Columbus, OH. Below is what the official statistics say about living and working there.

How Columbus compares. Among the 100 largest places in Ohio, Columbus is #1 by population, #92 for homeownership (#1 = highest), #12 for long commutes (#1 = fewest), #81 for rent (#1 = cheapest). Its county, Franklin County, is #4 of 88 counties for average pay ($73,180).

The place in numbers

Columbus has 914,802 residents (ACS 2020–2024), about 7.7% of the population of Ohio. It covers 222 square miles of land, which works out to roughly 4,129 people per square mile. The median age is 33.2, 16% younger than the state median (33.2 against 39.7).

Housing

The median gross rent is $1,295 a month (rent plus utilities), 25% above the state median ($1,295 against $1,034). Over a year that is 23.5% of the median household income. US housing guidance treats housing as affordable when it takes 30% of income or less, so the typical household is under that line. The median home value is $252,900, which is 3.8 times the median household income ($66,082); a ratio under 4 usually means ownership is within reach for many households. 44.1% of households own their home, 34% below the state average (44.1% against 67.2%). A low ownership share points to a rental-heavy market with more apartments and shorter stays.

Work and pay

The Columbus, OH metropolitan area has 1,105,580 jobs in the BLS wage survey, and the median pay across all occupations is $51,340 a year, about the same as the national median ($51,340 against $50,980). The biggest occupation groups are office and administrative support (121,850 jobs, median $47,890); transportation and material moving (118,690 jobs, median $43,980); food preparation and serving related (95,180 jobs, median $33,540). The area is most specialised in transportation and material moving (1.2 times) and healthcare practitioners and technical (1.2 times), where the share of workers is above the national share. The best-paying groups with at least 5,000 jobs are management ($111,840) and computer and mathematical ($104,470). In 2026M09 the unemployment rate of Franklin County was 3.4%. 70.0% of residents aged 16 and over are in the labour force. The city lies in Franklin County; its jobs, pay by industry and GDP are on the county page.

Getting around

Among workers, 67.7% drive alone, 1.9% use public transit, 2.5% walk, 18.3% work from home. 6.1% of workers commute 45 minutes or more, 43% below the state average (6.1% against 10.8%). Remote work is more common than in the state as a whole, which widens the set of employers a resident can work for without moving.

People and education

38.2% of adults aged 25 and over hold a bachelor's degree or higher, 21% above the state share (38.2% against 31.5%). 15.0% of residents were born outside the United States, 187% above the state share (15.0% against 5.2%). The poverty rate is 18.1%, 36% above the state rate (18.1% against 13.3%).

Climate

The warmest month is Jul, averaging 74°F (23.4°C), and the coolest is Jan at 27°F (-2.6°C). About 985 mm (39 inches) of precipitation falls in a year; May is the wettest month (105 mm) and Feb the driest (62 mm). These values come from NASA satellite-based climatology on a grid of about 50 km, so they describe the wider area, not a weather station in the city.

Nearby cities to compare

Closest cities in this guide: Whitehall (5 miles, rent 12% lower); Upper Arlington (5 miles, rent 23% higher); Gahanna (7 miles, rent 13% higher); Grove City (9 miles, similar rent). Rent differences are against Columbus; use the Compare tab to put any two cities side by side.
