Document Summary
Based on chapters 9, 10, 11 and 12. Urban growth: occurs when rates of growth between urban and rural populations are about the same over the long term and over wide areas. Urbanization: occurs when urban growth rates outstrip rural growth rates through some combination of natural increase in population and rural to urban migration rates. Compromised of three stages described by rates of growth (how fast a population is becoming urban) and levels of growth (what share of population is urban). Changes associated with urbanization: demographic changes: natural increase and migration, economic changes: economic activity leads to innovation, urban changes: size and characteristics of population. The demographic transition: a simple model that describes the interplay between births, deaths and natural increase, and the resultant stages in which a population ends up. Pop growth = (birth deaths) + (in-migration out-migration) Pop growth = natural increase + net migration.
