Questions to Think About
“The Push-Pull Theory”
Lee's laws divides factors causing migrations into two groups of factors: Push and pull factors. Push factors are things that are unfavorable about the area that one lives in and pull factors are things that attract one to another area.
Push Factors

Primitive conditions Desertification
Famine or drought Political fear or persecution
Slavery or forced labor
Poor medical care Loss of wealth
Natural disasters Death threats
Lack of political or religious freedom
Pollution Poor housing
Landlord/tenant issues

Since the 1950’s, this movement of people to the suburbs has increased, especially in Europe and the USA.
