Population growth rate (PGR) is the increase in a country’s population during a period of time, usually one year, expressed as a percentage of the population at the start of that period. It reflects the number of births and deaths during a period and the number of people migrating to and from a country. | |

* Population growth rates are much higher in most low- and middle-income countries than in most high-income countries. * There will be more than 1 billion more people in the world in 2015 than there were in 2000 (as population grows from about 6 billion to 7.1 billion), and six out of seven of these people will live in low- and middle-income countries. * Although the population growth rate for developing countries has been decreasing for several decades, the number of people added to the population each year has been increasing because the population base has become larger. * Countries that have a large proportion of their population in their childbearing years often experience population momentum. Even if couples have only enough children to replace themselves when they die, the population will continue to grow and will not stabilize until the younger group ages beyond their childbearing years. * Birth rates tend to fall when parents have access to family planning, health care, education and jobs. * Population growth can make it more difficult to raise standards of living in some countries and can put pressure on the environment resulting in pollution. * Two of the most successful strategies for reducing fertility rates are providing greater access to primary health care and promoting education for girls and women|
