General Notes: Data for more counties are typically available in years of the Census of Governments, such as 1997, 2002, and 2007. As a result, the median value is typically lower for those years due to the influx of smaller governments. Some data series from this source may also see an increase in counties in 2000, leading to a similar drop in the median value. *Median value gives the value for the "average" county for this metric, the 50th percentile of all counties reporting data. **Construction, maintenance, and operation of highways, streets, and related structures, including toll highways, bridges, tunnels, ferries, street lighting, and snow and ice removal. However, highway policing and traffic control are classed under police protection.
