The discrepancy is particularly obvious among people over fifty: men account for 7.1 percent of the country's total population and women for less than 5 percent.This figure reflects the secondary status of females in Pakistani society, especially their lack of access to quality medical care.Pakistan's extremely high rate of population growth is caused by a falling death rate combined with a continuing high birth rate.
Thus population planning was a dual effort led by the Family Planning Association and the public sector.
Pakistan's population is expected to double between 19.
These figures are estimates, however, because ethnic unrest led the government to postpone its decennial census in 1991.
There is an average of 146 persons per square kilometer, but the density varies dramatically, ranging from scarcely populated arid areas, especially in Balochistan, to some of the highest urban densities in the world in Karachi and Lahore.
About 68 percent of the population lived in rural areas in 1994, a decrease of 7 percent since 1970.
