Blackmans has a population of 623, making it the 13th largest place we list in Barbados. It is in Saint Joseph.
Blackmans holds 0.22% of Barbados's 282,724 people. Bridgetown, the largest place we list there, is 158 times its size. The World Gazetteer published 623 for Blackmans in 2005 and GeoNames still carries that same figure, so there is no measured change to report.
The 2005 figure comes from the World Gazetteer archive restored on this site. Why figures differ.

Figures are the latest available in GeoNames (CC BY 4.0), which draws on national censuses of varying dates — treat them as recent, not same-year. Country totals are UN World Population Prospects 2024 (medium variant) where the UN lists the country separately; the handful it reports under a parent state keep a GeoNames figure and are marked as such.
