ODOT Division of Small Business & External Workforce DevelopmentLocations of Advertising Device Control (ADC) Permits along the state highway system. ADC Permits ensure advertising devices meet established criteria for size, lighting, and spacing of signs, displays, and devices. Enacted in 1965, the Highway Beautification Act federally requires all states to maintain effective control over all outdoor advertising. Through an agreement with the federal government and as defined in the Ohio Revised Code and Ohio Administrative Code, the Ohio Department of Transportation is responsible for this oversight along controlled interstate and federal-aid primary highways in the state.
Advertising Device Control Permitting SpecialistsODOT's Adjusted Urbanized Areas are US Census Urban Area boundaries expanded through a cooperative process by responsible state and local officials. Urbanized boundaries are used to determine a roadway’s functional class, federal aid eligibility, and speed limit transition points, in accordance with 23 U.S.C. 101 and O.R.C 4511.21.
ODOT Technical ServicesODOT's inventory of roadway segments for the Adopt-A-Highway Program. Adopt-A-Highway is one of the methods in which ODOT controls litter and to keep the state's highways beautiful. The program allows volunteer groups to adopt a two-mile section or an interchange along a state, federal, or interstate route.

ODOT Office of Transportation and Economic Development, ELLIS ProgramActive transportation planning aims to provide communities safe and convenient access to home, work, school, recreation, and transit via walking and biking. This dataset contains composite scores for active transportation demand and need. Scores are derived from quantifying factors that generate bicycle and pedestrian movement, and can be used to inform and prioritize. Factors considered in demand analysis include: employment density, retail employment density, population density, park density, presence of existing active transportation, presence of colleges/universities, and poverty levels. Scores are applied at the geographic level of census block group.

US Census Bureau. This product uses the Census Bureau Data API but is not endorsed or certified by the Census Bureau. www.census.gov
American Community Survey figures on how people live and work in every Ohio census block group — a neighborhood-sized area of roughly 1,200 people. Covers income, poverty, education, employment, commuting (how people get to work, what time they leave home, and whether they work in their own town, county or state), vehicle access, housing cost, internet access and health insurance, including Medicaid, in six five-year releases spanning 2010 through 2024, all reported on 2020 boundaries so the periods can be compared. These are survey estimates rather than a complete count, so figures for any one small area are approximate.
US Census BureauPopulation, race and ethnicity, and housing occupancy for every Ohio census block group — a neighborhood-sized area of roughly 1,200 people — at the 1990, 2000, 2010 and 2020 censuses. All four years are reported on 2020 boundaries, so a neighborhood can be tracked across three decades of growth or decline. The census is a complete count rather than a survey, so there are no sampling margins of error — but the earlier figures were apportioned onto those 2020 boundaries, which carries an uncertainty of its own, and the data set records how much of each neighborhood's figure was apportioned that way.
US Census BureauBoundaries of Ohio's census block groups as drawn for the 2020 census. A block group is the smallest area the Census Bureau publishes socioeconomic data for — roughly 600 to 3,000 people, about 1,200 in Ohio, typically a few residential streets — and it is the geography the census population and American Community Survey figures are mapped on.
US Census BureauOhio's 88 counties as the Census Bureau draws them, with each county's land and water area and the freight region it belongs to in the Commodity Flow Survey (CFS), the Bureau's survey of goods shipped by businesses. The freight regions are the ones the Freight Analysis Framework's flows are reported for, so this is how a county is placed in those flows, and it is a reliable county outline and name list for mapping or summarizing anything else by county.
US Census BureauThe Census Bureau's official estimate of how many people of each age, sex, race and Hispanic origin lived in each Ohio county on July 1 of every year since 1970. Use it to see how a county is ageing, how many children, working-age adults or older residents it has and how that has changed, or how its racial and ethnic make-up has shifted over half a century. The years before 2020 are the Bureau's revised figures for those decades, made after each census; the earlier decades distinguish fewer races, and the 1970s and 1980s do not record Hispanic origin.
US Census BureauThe Census Bureau's official population estimate for each Ohio county on July 1 of every year since 1970, with what drove each year's change since 2000: births, deaths, people moving in from abroad and people moving in from or out to the rest of the country. Use it for a county's current population, for half a century of growth or decline, and for whether a county is growing because people are moving there or because births outnumber deaths. The years before 2020 are the Bureau's revised figures for those decades, made after each census, and the 1970 and 1980 censuses' own counts are kept beside them.
US Census BureauThe divisions of each Ohio county as the Census Bureau draws them each year: townships and towns in the states where those are local governments, and statistical county divisions where they are not. Together they cover the whole state with no gaps, so they are the local unit for mapping or summarizing anything across rural and urban areas alike, and each one's current population is in the Bureau's annual population estimates, which join to these outlines.
US Census BureauThe Census Bureau's official population estimate for every Ohio city, village and town, and for every township or town where those are local governments, on July 1 of every year since 1990, with the 1980 and 1990 censuses' counts beside them. Use it for a municipality's current population, to rank places by size or growth, or to see which communities have been gaining or losing people over four decades. The years from 2000 to 2019 are the Bureau's revised figures for those decades, made after the 2010 and 2020 censuses; the 1990s figures were never revised.
US Census BureauThe boundaries of Ohio's cities, villages, boroughs and towns as the Census Bureau draws them each year, together with the named unincorporated communities it calls census-designated places. Use them to outline a municipality on the map, to find which city or village a road, bridge or facility is in, or to summarize anything else by city and village. Each place's current population is in the Bureau's annual population estimates, which join to these outlines.
US Census BureauOhio's five-digit ZIP Code areas as the Census Bureau draws them for the 2020 census, called ZIP Code Tabulation Areas (ZCTAs). They are the closest public outline of a ZIP Code: use them to place an address, a street or a facility given by ZIP Code on the map, or to summarize anything else by ZIP Code. They approximate the Postal Service's delivery areas rather than reproduce them, and ZIP Codes that serve only post office boxes or a single building have none.

Ohio Geographically Referenced Information Program (OGRIP / DAS). ogrip.oit.ohio.gov
The land-use classes found on Ohio's parcels — agricultural, mineral, industrial, commercial, residential, exempt, tax-abated, public utility and unclassified — with the plain-English label for each code and a count of how many parcels carry it. Use it to read the parcel data by what land is actually used for.
OGRIP (Ohio Geographically Referenced Information Program / DAS)Property boundaries for all 88 Ohio counties, assembled by Ohio's Geographically Referenced Information Program (OGRIP) from what each county auditor maintains into a single statewide layer. Every parcel carries its land-use class, its size and its county, which makes this the base layer for questions about what the land along a corridor or around a project is used for. It is a public extract, so it carries no owner names and no assessed values.

Where Ohio's workers live and where they go to work: job counts for every pair of home and workplace neighborhood (a census block group of roughly 1,100 people), from the Census Bureau's LEHD program. This is the data behind commute-shed questions — which communities feed a job center, how far people travel to a corridor, how those patterns have shifted. Covers workplaces in Ohio for 2002, 2007, 2010, 2014, 2019, 2021 and 2023.

US Census Bureau, Longitudinal Employer-Household DynamicsJobs located in each Ohio neighborhood — a census block group of roughly 1,100 people — broken out by industry, age, earnings, race, ethnicity, education and sex, and — for private-sector jobs — by the age and size of the employer. This is where work actually happens rather than where workers live, which makes it the starting point for job-center, corridor and economic-development questions. Counts come from state unemployment-insurance payroll records, not a survey, and cover 2002 through 2023.

FAFFAF (BTS freight flows)5 data sets
Bureau of Transportation Statistics, Freight Analysis Framework. www.bts.gov
A directory matching each of Ohio's 88 counties to the freight region it belongs to. Ohio is divided into six freight regions — Cincinnati, Cleveland, Columbus, Dayton, Toledo, and the remainder of the state — and this is how you find which one a given county falls in.
Census Bureau CFS geography / BTS FAF6The list of transportation modes used in the freight flow data — truck, rail, water, air, pipeline, multiple modes and mail — so freight volumes can be reported by how the goods actually move.
Bureau of Transportation StatisticsEstimated freight moving to, from and within Ohio in 2022: how much tonnage and how much value travels between each pair of origin and destination regions, broken out by what the commodity is and how it moves, including truck, rail, water, air, pipeline and multiple-mode shipments. Domestic shipments, imports arriving in Ohio and exports leaving from Ohio are all included. These are shipments between regions, not traffic measured on any particular highway; for designated freight routes see the National Highway Freight Network.
Bureau of Transportation StatisticsThe regions used throughout the freight flow data: 134 areas covering the United States plus 8 world regions for international trade. Ohio is split into six of them — Cincinnati, Cleveland, Columbus, Dayton, Toledo, and the remainder of the state — and those six are the ones drawn on the map. Each is a group of whole counties, so they do not line up with metropolitan planning organization boundaries, census urban areas or state transportation department districts.
Bureau of Transportation StatisticsPlain-English names for the commodity groups used in the freight flow data — the Standard Classification of Transported Goods, 42 categories running from cereal grains and coal through machinery, motorized vehicles and mixed freight. Use it to report freight volumes by what is being shipped.

NTMNTM (BTS transit routes and stops)3 data sets
U.S. Department of Transportation, Bureau of Transportation Statistics, National Transit Map, with data from City of Lawndale; and Via Mobility Services under CC BY 3.0 US (https://creativecommons.org/licenses/by/3.0/us/). Changed: cut to one state's routes, stops and agencies, and fields recoded. www.bts.gov
The transit agencies whose fixed-route service reaches Ohio, with each one's headquarters and its National Transit Database ID, the key to its ridership, service and cost figures.
Bureau of Transportation StatisticsThe paths of the fixed-route bus, rail, streetcar, subway and ferry services that run in Ohio, as the transit agencies publish them, compiled nationally by the Bureau of Transportation Statistics. Good for seeing where transit runs, which kinds of service reach an area, and how far each route goes.
Bureau of Transportation StatisticsEvery fixed-route transit stop and station in Ohio, with the kinds of service that call there and whether the agency marks it wheelchair accessible. Good for measuring who lives or works within walking distance of transit, and where accessible boarding is missing.

Ohio Department of Development, Office of Research. development.ohio.gov
The state's own projection of each Ohio county's population from 2020 to 2050, in five-year steps, by five-year age group and by sex. Use it to see where the population is expected to grow or shrink over a long-range planning horizon, and which age groups drive the change, such as where older residents who rely on transit and paratransit will be most numerous, or where the school-age population is falling.

NCESNCES (public schools)1 data set
U.S. Department of Education, National Center for Education Statistics, Education Demographic and Geographic Estimates (EDGE) and Common Core of Data (CCD). Changed: cut to one state, the locations joined to the administrative data by school, and codes recoded. nces.ed.gov
Every public elementary and secondary school in Ohio, charter schools included, with its location, the grades it teaches, how many students it enrolls by grade and race, its teachers, and how many of its students qualify for free or reduced-price lunch, for each school year since 2017–18. Good for planning around schools: safe routes and walking distance, bus and transit access, the traffic a school draws, where enrollment is growing or shrinking, and where low-income students are concentrated.

BPSBPS (Census building permits)2 data sets
U.S. Census Bureau, Building Permits Survey. Changed: cut to one state, reshaped to one row per county or permit office per year, and footnote marks moved out of the names. www.census.gov
How many new homes building permits authorized in each Ohio county every year since 1990, split into single-family houses, duplexes, small 3–4 unit buildings and apartment buildings of five units or more, with the number of buildings and their construction value. Use it to see where housing is being added, how fast, and in what form, as an early sign of growth in households, travel demand and school enrollment, and to compare counties or follow one county's building boom or slowdown over three decades.
US Census BureauHow many new homes each Ohio city, village, township, town or county permit office authorized every year since 1992, split into single-family houses, duplexes, small 3–4 unit buildings and apartment buildings of five units or more, with the number of buildings and their construction value. Use it to find the communities where housing growth is concentrated, to follow one community's development over time, and to anticipate the new trips, utility demand and school enrollment that new homes bring below the county level.

QCEWQCEW (BLS employment and wages)2 data sets
U.S. Bureau of Labor Statistics, Quarterly Census of Employment and Wages. Changed: cut to one state, suppressed figures stored as empty rather than zero, and the over-the-year, taxable wage and contribution columns dropped. www.bls.gov
How many people worked in each Ohio county and industry, how many workplaces employed them and what they were paid, as averages for every year since 1990, from the near-complete count of jobs that employers report for unemployment insurance. Use it to compare counties and industries year by year, to follow an industry's jobs and average pay over three decades, and to see how much of a county's payroll one industry such as manufacturing or health care carries, down to individual industries.
U.S. Bureau of Labor StatisticsHow many people worked in each Ohio county and industry, how many workplaces employed them and what they were paid, every quarter since 1990, from the near-complete count of jobs that employers report for unemployment insurance. Use it to see which industries a county's jobs and payroll depend on, where an industry such as warehousing or manufacturing is growing, and how a local economy moved through a plant opening or a recession, down to individual industries.

US Census Bureau. This product uses the Census Bureau Data API but is not endorsed or certified by the Census Bureau. www.census.gov
The Census Bureau's official estimate of how many people of each age, sex, race and Hispanic origin lived in every state, the District of Columbia and the United States as a whole on July 1 of every year since 1970. Use it to set a state's age profile or racial and ethnic make-up beside its neighbours' or the nation's, to rank the states by their share of older residents or children, or to see how quickly each has aged over half a century. The earlier decades distinguish fewer races, and the 1970s and 1980s do not record Hispanic origin.
US Census BureauThe Census Bureau's official population estimate for every state, the District of Columbia and the United States as a whole on July 1 of every year since 1970, with what drove each year's change since 2000: births, deaths, people moving in from abroad and people moving between states. Use it to set a state's growth beside its neighbours' or the nation's over half a century, to rank the states, or to see whether a state is gaining people from the rest of the country or losing them to it.
US Census BureauThe Census Bureau's boundary of every state and the District of Columbia, with each one's land and water area and the Census region and division it belongs to. Use it to draw any state-by-state figure as a map of the whole country, such as a state's growth beside its neighbours', or to outline a state on a map of its own data.

NAICSNAICS (BLS industry codes)1 data set
U.S. Bureau of Labor Statistics, Quarterly Census of Employment and Wages industry titles. www.bls.gov
The names of the industry codes the employment data is reported by, from all industries together down to some 1,400 detailed industries: the North American Industry Classification System (NAICS) that BLS and the Census Bureau use, with BLS's broader goods-producing and service-providing domains and supersectors above it. Use it to put readable names on job and wage figures, and to move between a detailed industry and the broader group it belongs to.

- State Highway Fatal & Serious-Injury Crash Rate 2021–2025Color every state-highway segment by its fatal and serious-injury crash rate per 100 million vehicle miles over 2021–2025, in quintiles, and mark the worst 25 stretches on top.
- Commute Flows Into Top Job-Surplus Block GroupsFind the ten block groups with the largest excess of jobs over resident workers and draw the commute flows feeding each one, weighted by worker count.
- MORPC Fatal and Serious Injury Crashes 2021–2025For the MORPC area around Columbus, compute fatalities, serious injuries, each as a count and as a rate per 100 million vehicle miles, and non-motorized fatalities and serious injuries, for each of the last five years, and map where they fall.
- NOACA Corridor Level of ServiceRank the congested corridors in the NOACA area around Cleveland by delay and vehicle hours travelled, and show the level of service on each.
- Eastgate Hazard-Exposed Structures and RoutesMap the structures and routes in the Eastgate area around Youngstown exposed to slope failure, scour and flooding, and show what traffic depends on each.
- NOACA $10M Safety Program PicksThe NOACA area around Cleveland has $10 million for safety improvements on state routes. Choose where to spend it to prevent the most fatal and serious-injury crashes, using 2021–2024 crashes and two countermeasures. The first is centerline and shoulder rumble strips at $25,000 per mile, which cut lane-departure crashes by 30% on two-lane segments posted 45 mph or higher. The second is roundabouts at $2 million each, which cut angle crashes by 60% at intersections. Rank candidates by crashes prevented per dollar, pick the best mix within the budget, and map the chosen segments and intersections with the expected crashes prevented at each.
- District 4 Pavement Selections: Optimized vs Worst-FirstODOT District 4 has $40 million to spend on state-system pavement next year. Choose which segments to treat to keep the most traffic off poor pavement, counting the benefit as the daily vehicle-miles on each segment that would move out of a PCR below 65. Assume a mill-and-fill costs $300,000 per lane-mile and fixes segments rated 55 to 64, and full-depth reconstruction costs $1.2 million per lane-mile and is the only fix below 55. Compare your selection with a worst-first list that spends the same budget on the lowest-rated pavement, report how many vehicle-miles each one fixes, and map both.
- MVRPC Fatal and Serious Injury Crashes 2021–2025For the MVRPC metropolitan planning area around Dayton (the MVRPC polygon in the MPO data set, which covers Montgomery, Miami, Greene and the northern part of Warren County), count fatal and serious-injury crashes for each year from 2021 through 2025, counting each crash report once by its crash severity. Use the same scope as MVRPC's Safety Action Plan: leave out crashes on restricted-access freeways (functional class 1 and 2, which covers I-70, I-75, I-675 and the freeway sections of US 35 and SR 4), crashes on freeway ramps, and crashes with no location. Split each year into urban and rural, where urban means inside ODOT's Adjusted Urbanized Areas. Show one table with a row per year and columns for urban fatal, rural fatal, urban serious injury, rural serious injury, and total fatal plus serious injury. Then show a second table, by year, of the fatal and serious-injury crashes that the freeway and ramp exclusions removed. Map the counted crashes colored by severity, draw the excluded freeway crashes in gray, and outline the MVRPC boundary and the urbanized areas.
