Population Growth

% Change in Food Demand

% Change in Population Growth + % Change in Income x IEoD.

Crude Birth Rate (CBR)

Number of births in a geographic area in a given year per 100 people.

Demographic Momentum

A reason why Crude Birth Rates decrease slowly, due to high total fertility rates leading to population growth in future generations.

Replacement Rate of CBR

The rate at which the population exactly replaces itself from one generation to the next, typically defined as 2.1.

Rate of Natural Increase (NI)

Calculated as Crude Birth Rate (CBR) minus Crude Death Rate (CDR), does not account for migration.

Total Fertility Rate (TFR)

The average number of children that would be born to a woman over her lifetime based on current birth rates.

Factors Leading to Decrease in TFR

Female empowerment, decreasing infant mortality rates, increased standards of living, and urbanization.

Rule of 72

A method to estimate the number of years it takes for an investment to double by dividing 72 by the annual interest rate.

Impact of Population Growth on Food Demand

As population growth decelerates, food demand will be driven more by improved living standards than population growth.

Rate of Population Change

Population growth is at a decreasing rate because the birth rate is dropping, not necessarily due to an increase in the death rate.
