Population

The Darby Watershed was one of the last areas of the state that was developed in the 1800s and has maintained a relatively small population. According to block level (smallest spatial unit of census data) 2000 census data, the population of the watershed is approximately 70,900. No large city is lies entirely within the watershed. Only small percentages of Columbus, Hilliard, and Marysville lie within the watershed. The population density of the watershed is approximately one person for every five acres of land. For comparison, the population density in the state of Ohio is one person for every 2.3 acres. Additional population density comparisons are provided in the far left column of Figure 21 for portions of counties in the Darby Watershed.
