Question

1. what does it mean to have a poulation growth rate greater than zero?

it is impossible to tell from the data provided

birthrate + immigration > death rate + emigration

birthrate + immigration = death rate + emigration

birthrate + immigration < death rate + emigration

Explanation:

Define population growth components

Using the Demographic Equation and Population Growth Rate knowledge points

$$ \text{Population Change} = (\text{Birthrate} + \text{Immigration}) - (\text{Death Rate} + \text{Emigration}) $$

Analyze a growth rate greater than zero

Using the Population Growth Rate knowledge point

$$ \text{Population Change} > 0 \implies \text{Birthrate} + \text{Immigration} > \text{Death Rate} + \text{Emigration} $$

Match with the given options

Using the Demographic Equation knowledge point
The inequality matches the second option: \(\text{birthrate} + \text{immigration} > \text{death rate} + \text{emigration}\).

Answer:

• (A) It is impossible to tell from the data provided
• (B) birthrate + immigration > death rate + emigration (Correct answer)
• (C) birthrate + immigration = death rate + emigration
• (D) birthrate + immigration < death rate + emigration
