Sociology Preliminary DEMOGRAPHY

Several developments of techniques in the field of mathematics encouraged attempts to formulate mathematical laws of population growth. The most important mathematical theory is the ‘theory of logistic law’ which is given by

Pearl and Reed

H. Spencer

Ginni

A. Dumont

Explanation:

- Option 1: Pearl and Reed

- Raymond Pearl and Lowell Reed developed the logistic growth model in the 1920s. This model describes how populations grow in an environment with limited resources.

- It predicts an S-shaped curve where growth starts exponentially, slows as resources become scarce, and finally stabilizes.

- Option 2: H. Spencer

- Herbert Spencer was a philosopher known for coining "survival of the fittest."

- He didn't formulate the logistic law of population growth.

- Option 3: Ginni

- This name doesn't have a recognized connection to the logistic growth model.

- Option 4: A. Dumont

- Arsène Dumont was a demographer known for his work on population theories but not specifically for the logistic law.
