Editing Arapaho (section)

== Population history ==
There are no references to the numbers of the Arapaho previous to the 19th century. M. R. Stuart in 1812 estimated the Arapaho at 3,050 warriors (therefore around 15,250 people). [[Jedidiah Morse]] in 1822 reported 10,000 Arrapahays, 7,000 Kaninavisch (another name for the Arapaho), 1,500 Castahana and 1,500 Pastanownas (possibly related tribes). Indian Affairs gave the Arapaho at 3,045 people in year 1880, 2,298 in year 1885, 1,925 in 1890, 1,869 in 1895, 1,782 in 1900, 1,768 in 1905 and 1,753 in 1910.<ref name="Krzywicki">{{Cite book |last=Krzywicki |first=Ludwik |url=https://babel.hathitrust.org/cgi/pt?id=uc1.b4381154&view=1up&seq=346&skin=2021 |title=Primitive society and its vital statistics |publisher=Macmillan |year=1934 |series=Publications of the Polish Sociological Institute |location=London |pages=448}}</ref>
