The difference in population for Tlokwe is calculated as follows:

$162,762 - 128,353 = 34,409$.

To calculate the number of elderly (65+) people in the Blouberg municipality in 2001, we use the percentage of elderly people (6.1%) multiplied by the total population of Blouberg in 2001:

$0.061 imes 171,721 = 10,474$.

The probability that a randomly chosen person from the Breedevallei municipality in 2011 is working is calculated as follows:

P = rac{113,406}{171,721} \approx 0.6613. Thus, the simplified fraction for the probability is approximately 66.13%.

Blouberg municipality showed the highest percentage increase in electricity consumption from 2001 to 2011.

The average population growth rate for Breedevallei can be calculated using the formula:

$\text{Gemiddelde bevolkingsgroei} = \frac{\text{verskil in bevolking}}{\text{totale bevolking in 2001}} \times 100 = \frac{(166,825-146,387)}{146,387} \times 100 \approx 13.96\%$.

The area of the Tlokwe municipality in 2011 is calculated as:

$\frac{\text{bevolking}}{\text{bevolkingsdigtheid}} = \frac{128,353}{61} \approx 2,098 \text{ km}^2$, rounding to the nearest km² gives approximately 2,098 km².
