Population growth and unemployment are not correlated. An increase in population leads to a decrease in unemployment. There will be tax breaks for families with fewer children. Girls will be required to finish high school. The government will impose a limit of only one child. The government will provide free family planning. There are more adult women than adult men. There are equal numbers of adult men and adult women. There are more adult men than adult women.
