Joe, those statistics are regarding demographics (i.e. working age). It's saying that the immigrant population age distribution is slanted more towards younger populations than the Alaskan-born population. It has nothing to do with lifestyle choices or culture. If you were to tell me that that figure (39%) is inflated because the report doesn't take into consideration subsistence living in rural Alaskan communities, then we could have a reasonable discussion. In that case, I would counter that given that over half Alaska's population is congregated in urban South Central (Anchorage, Valley and Kenai Peninsula) , Interior (Fairbanks) and Southeast (Juneau, Sitka, Ketchikan, etc), the overall assessment that the immigrant population has a higher percentage of working-age individuals than does the Alaskan-born population more than likely still holds but is lower than the 39% reported here.
