Question

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

birthrate + immigration < death rate + emigration

birthrate + immigration = death rate + emigration

birthrate + immigration > death rate + emigration

it is impossible to tell from the data provided

Explanation:

Define population growth rate

In Human Geography, the population growth rate measures how fast a population changes over time. It is determined by the balance between factors that add individuals to a population and factors that remove them.

Identify factors of population change

A population increases through births (birthrate) and people moving in (immigration). Conversely, a population decreases through deaths (death rate) and people moving out (emigration).

Formulate the growth equation

The overall change in a population can be represented by the demographic equation:

$$\text{Population Change} = (\text{birthrate} + \text{immigration}) - (\text{death rate} + \text{emigration})$$

Analyze zero growth rate

For the growth rate to be exactly zero, the total number of people entering the population must equal the total number of people leaving. Mathematically, this means:

$$\text{birthrate} + \text{immigration} = \text{death rate} + \text{emigration}$$

Match with the options

Comparing our equation to the choices, the second option correctly states that the sum of birthrate and immigration equals the sum of death rate and emigration.

Answer:

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