  3. 3. In some LEDCs the government is encouraging couples to have smaller families. This means the birth rate has fallen.
  4. 4. The largest category of people were born about 40 years ago. In this country there is a low Birth Rate and a low Death Rate. This population pyramid is typical of countries in the richer parts of the world (MEDCs.) Male Female Population in millions In this country the number of people in each age group is about the same.
  5. 5. Population in millions Male Female In this country the birth rate is decreasing. In the future the elderly people will make up the largest section of the population in this country. This is happening more and more in many of the world’s richer countries.
