Population Dynamics, Migration Factors, and Urban Geography
Global Population Dynamics and Growth
World population grew very slowly before the 19th century. Birth rates were high, but death rates were also high. From the early 19th century, the death rate in developed countries fell due to improved medicine and better nutrition following improvements in agriculture, causing the world population to increase.
In the 20th century, there was rapid population growth, often referred to as the Population Explosion.
Regions with Low Population Growth
These regions typically have low population growth, often around 0.2%. This trend is linked to several factors:
- Low birth rate.
- More working women.
- Contraception is widely available.
- Families delay having children.
- It is expensive to raise a family.
- Social values are changing.
