Writing a character named Mack?
A boy named Mack was most likely born around 1942.
Where the counts come from: the US from Social Security card records from 1880 (names given to at least 5 babies in a year; years before about 1937 count fewer people, because the cards started then), and before 1880 from Douglas Galbi's tables of a census sample. England and Wales from the Office for National Statistics from 1996, and before that from Stephen Bush's study of local birth records, a sample of about 120,000 births a year (CC BY 4.0). Scotland from National Records of Scotland. Northern Ireland from NISRA. France from INSEE, first names and last names. Italy from ISTAT (CC BY 4.0), the top 50 names a year. Berlin from the city's open data (CC BY 3.0 DE), counting only the first of a child's names. UK figures are Crown copyright, used under the Open Government Licence. US last names from the 2020 census, and before 1850 from the 1790 census. Irish last names from Robert Matheson's report on the births of 1890.
