US Census in the context of 1790 United States census

Hayward is a city in Alameda County, California, United States, in the East Bay subregion of the San Francisco Bay Area. With a population of 162,954 as of 2020, Hayward is the sixth largest city in the Bay Area, and the third largest in Alameda County. Hayward was ranked as the 36th most populous municipality in California. It is included in the San Francisco–Oakland–San Jose Metropolitan Statistical Area by the US Census. It is located primarily between Castro Valley, San Leandro and Union City, and lies at the eastern terminus of the San Mateo–Hayward Bridge. The city was devastated early in its history by the 1868 Hayward earthquake. From the early 20th century until the beginning of the 1980s, Hayward's economy was dominated by its now defunct food canning and salt production industries.

The 1860 United States census was the eighth census conducted in the United States, starting June 1, 1860, and lasting five months. It determined the population of the United States to be 31,443,321 in 33 states and 10 organized territories. This was an increase of 35.6 percent over the 23,191,876 persons enumerated during the 1850 census. The total population included 3,953,760 slaves.

By the time the 1860 census returns were ready for tabulation, the nation was sinking into the American Civil War. As a result, census superintendent Joseph C. G. Kennedy and his staff produced only an abbreviated set of public reports, without graphic or cartographic representations. The statistics did allow the census staff to produce a cartographic display, including preparing maps of Southern states, for Union field commanders. These maps displayed militarily vital topics, including the white population, slave population, predominant agricultural products (by county), and rail and post road transportation routes.

A persistent poverty county is a classification for counties in the United States that have had a relatively high rate of poverty over a long period.

A 2009 U.S. federal law defined a persistent poverty county as one in which "20 percent or more of its population [has lived] in poverty over the past 30 years" according to the Census, which is done every 10 years. The Economic Research Service (ERS) of the U.S. Department of Agriculture categorizes non-metropolitan counties by their dominant economic foundation and by characteristic policy type. Persistent poverty counties are defined as those where 20% or more of the county population in each of the last four decennial Censuses had poverty level household incomes.

Pasquo is a neighborhood of Nashville, along State Route 100 in Davidson County, within Bellevue. It is incorporated as part of the Metropolitan Government of Nashville and Davidson County.

Formerly a rural area, Pasquo has experienced rapid growth in recent years as the Nashville suburbs expand westward. As Pasquo is neither an incorporated municipality nor a census-designated place, its population is not measured or reported by the US Census. Pasquo is home to "Radio Free Nashville," the low-power FM radio radio station WRFN-LP. WRFN was the seventh community radio barnraising of the Prometheus Radio Project.
