Replacement Rates for Rural-Farm Males Aged 25-69 Years, by Counties, 1940-50

Excerpts: Replacement rates are a means of showing how rapidly a population group is replacing itself during a period of time. For the group of working age, the replacement rate is the ratio of persons reaching working age to the persons of working age who die or retire during the specified time. Attached tables show replacement rates for men in the rural-farm population, 25-69 years of age for the decade 1940-50 in the United States. This is the age which includes most farm operators for only a comparatively few young men become farm operators before they have reached their 25th birthday, and relatively few continue as operators after they are 70 years old. For purposes of these computations it is assumed that a rural-farm man on reaching his 70th birthday, retires from active work.
