What are the stages of the Demographic Transition Model (DTM)?

The DTM consists of five stages: Stage 1 (High Fluctuating), Stage 2 (Early Expanding), Stage 3 (Late Expanding), Stage 4 (Low Fluctuating), and Stage 5 (Declining Population).

Which countries typically fall into DTM Stage 2?

Countries such as Afghanistan, many Sub-Saharan African nations, and Yemen are often in Stage 2, characterized by high birth rates and declining death rates.

How do you calculate population growth?

Population growth can be calculated using the formula: Population Growth = (Births - Deaths) + (Immigrants - Emigrants).

What is Malthus's theory on population growth?

Malthus theorized that population grows exponentially while food supply grows arithmetically, leading to inevitable famine unless population growth is controlled.

Common mistakes regarding the AP Human Geography Unit 2 test?

Students often confuse migration types, misunderstand the DTM stages, and mix up Malthusian theory with more modern population theories.

What is the Epidemiological Transition Model (ETM)?

The ETM explains the change in population health and disease patterns as countries progress through the DTM stages.

What are the US regions based on human geography?

The US can be divided into regions such as the Northeast, Midwest, South, and West, each with distinct demographic and cultural characteristics.
