Paris has been studying the demography of the united kingdom. the u. k. is very similar to the united states or sweden in that it is industrialized, has relatively long life expectancy, and infant mortality is low. which stage in the demographic transition theory would the u. k. fall into?

I will fall into "Stage 4".

Stage 4 is Post-transition, these societies are categorized by low birth and low death rates.The demographic transition theory is a summed up portrayal of the changing form of mortality, richness and development rates as social orders move starting with one statistic administration then onto the next. The term was first instituted by the American demographer Frank W. Notestein in the middle of 20th century.
