The theory of demographic transition explains the changes in population growth rates over time as a country develops economically and socially.
This theory was primarily developed by Warren Thompson.
In 1929, Warren Thompson first described the demographic transition model, outlining the shift from high birth rates and high death rates in pre-industrial societies to low birth rates and low death rates in societies with high levels of development.
Other theorists like Zelinsky (migration transition) and Ravenstein (laws of migration) made significant contributions to related demographic fields, but Thompson is credited with the foundational demographic transition theory.
Correct Answer Rationale: Warren Thompson is widely recognized as the originator of the demographic transition theory.
