The best available estimate I found says Oklahoma has about 29,695 Polish residents. A related source puts the figure at 29,790 , so a reasonable current range is about 29.7 thousand people.

Context

These numbers appear to refer to people with Polish ancestry or identity, not necessarily people born in Poland. Estimates can differ a bit depending on whether the source uses census ancestry data or a compiled demographic model.

Oklahoma context

One older Oklahoma history source noted that the state’s Polish population was much smaller in 1970, at 2,274 people, showing how much the community has grown over time. More recent county-level data also suggests concentrations in places like Oklahoma County and Canadian County.
