During recent years the following significant changes have occurred in the composition and distribution of population in Sully county: the total population has declined; the proportion in the younger age groups has decreased while the proportion in the older age groups has increased; the sex ratio has become more nearly equal; the percentage or foreign born has decreased; the birth rate has been sharply curtailed; and tenancy has increased. Some of these changes have come about as adjustments to changing social and economic conditions. Because a lag always exists between a changing population pattern and long established social institutional patterns, it is now recognized that some of these population changes call for widespread social readjustment.
