Because of a combination of land use (i.e. farming) and population growth Costa Rica had lost approximately 40% of its forest by 1990. Today only about 25% of the forest remain, and this is in protected areas.
Generally, population maps show the concentrations of population in different areas of the world.
Pakistan is 6th largest population in the world and the latest figures show Pakistan's growth rate has risen to an alarming 2.5 percent. This means Pakistan might become the 3rd largest population after China and India by 2050. An independent study by World Bank carried out in June 2011 reports that by 2020 half of Pakistan's population will be of age 15 years or less. This situation requires an enormous investment in education and human development sector. Figures show a huge gap between demand and supply of educational resources, schools, universities, institutes etc

Young people can show a responsible attitude towards population growth by advocating for and practicing family planning, educating themselves and others about the importance of sustainable population growth, and supporting policies and initiatives that promote access to reproductive health services. They can also engage in environmental conservation efforts to mitigate the impact of population growth on the environment.

The shape of the age structure graph can show if a country is growing rapidly,slowly,or negatively.It can also show zero growth.
are you talking about U.S History? that would be "growth in population, concentrated in cities"

The future of future population growth is difficult to predict. Scientists use a variety of data and assumptions to develop hypothesis about future growth. Many predictions in specific countries are partly based on a characteristic called age structure. The age structure of a population is the proportion of people in different age groups.
scientist show that the rate of the population of animals now could rise by 10% and further take over the world.
Short life-history organisms have a rapid population increase and decline caused by unpredictable enviroments. Long life-history organisms show slow population change within stable enviroments.
The one for the map about climate changes is called a climate map, while the map that shows information about population growth (or changes) is called a thematic map.
