text: Population decline
Contemporary decline by country
The table below shows that a number of countries are declining in population , in particular Puerto Rico , Latvia , Lithuania and Venezuela . The term population used here is based on the de facto definition of population , which counts all residents regardless of legal status or citizenship , except for refugees not permanently settled in the country of asylum , who are generally considered part of the population of the country of origin . This means that population growth in this table includes net changes from immigration and emigration . For a table of natural population changes , see list of countries by natural increase .
A population decline (or depopulation) in humans is a reduction in a human population caused by events such as long-term demographic trends, as in sub-replacement fertility, emigration, for example as a result of economic recession, urban decay, rural flight, food resource decline or high death rates due to violence, disease, or other catastrophes. Depopulation in humans can be largely beneficial for a region, allocating more resources with less or no competition for the new population. In addition to exempting the disadvantages of overpopulation, such as increased traffic, pollution, real estate prices, environmental destruction, etc. Per-capita wealth may increase in depopulation scenarios, in addition to improvement of environmental quality-of-life indicators such as improved air and water quality, reforestation, return of native species and mangroves, reduction of carbon emissions, etc. The accompanying benefits of depopulation have been termed shrink and prosper, with benefits being similar to the post-Civil War Gilded Age, post-World War I economic boom, and the post-World War II economic boom.
