Between 1880 and 1900, the urban population of the United States rose from 28% to 40%, and reached 50% by 1920, in part due to 9,000,000 European immigrants. After 1890 the US rural population began to plummet, as farmers were displaced by mechanization and forced to migrate to urban factory jobs.
The 1980 United States census, conducted by the Census Bureau, determined the resident population of the United States to be 226,545,805, an increase of 11.4% over the 203,184,772 persons enumerated during the 1970 census. [1]
By 1980, the population trends of urban decline and suburbanization that started in the 1950s were at their peak. This was the second census (see also 1960) to show a decline in the combined total population of the top ten cities, with 1,142,003 (5.2%) fewer people than the 1970 Census' top ten cities, mostly due to the large drop in population ...

The 1980s was an era of tremendous population growth around the world, surpassing the 1970s and 1990s, and arguably being the largest in human history. During the 1980s, the world population grew from 4.4 to 5.3 billion people. There were approximately 1.33 billion births and 480 million deaths.
Some estimates extend their timeline into deep prehistory, to "10,000 BC", i.e., the early Holocene, when world population estimates range roughly between 1 and 10 million (with an uncertainty of up to an order of magnitude). [3] [4] Estimates for yet deeper prehistory, into the Paleolithic, are of a different nature.
