The Malthusian model of population growth describes:
(A) represents Stage I, characterized by high birth and death rates in less developed regions.
(B) represents Stage II, where death rates decline while birth rates remain high.
(C) represents Stage III, where both birth and death rates begin to fall.
(D) is excluded from this model, as it implies a stable population with low birth and death rates.
Therefore, the correct answer is (b).

In an economy, exclusion of _______ may lead to under estimation of the value of Gross Domestic Product (GDP).
