 Amber Waves
Urbanization is defined as the increase of the percentage of people who live in Urban Areas. This may occur due to people moving from Rural Areas to Urban areas, or Rural Areas becoming Urban Areas in their own right (such as a growth in population). For example, artificially new cities such as Brazillia, Brazil turn a rural area into an urban area. Rapid urbanization may result in Rural Decay where rural areas fall into disarray due to a decreased or non-existent population.
Political Leanings of Rural Areas
Rural areas tend to be more conservative than cities in many countries. In the United States, heavily rural states such as Montanta and Kansas on the whole vote Republican while more urban states such as New York and California leant Democrat. Other countries follow the same trend such as in Britain and Japan where cities traditionally vote for the Labour Party and Democratic Party of Japan respectively (left-wing) and rural areas vote for the Conservative Party and Liberal Democratic Party respectively.
For all the bad tidings, there is one important development that could bode well for Democrats in some Southern states. While they may never get back the rural areas that once served as their bulwark, Southern Democrats are now competitive in some fast-growing suburbs in states that have a significant number of transplants. There was a reason why Obama won Virginia and North Carolina in 2008 -- both are filled with newcomers who are open to supporting either party.
