Use the data above to answer the questions that follow.

4.1.1 Determine the percentage increase in the total number of households from 2001 to 2011. (4)

4.1.2 State which household size matches EACH of the following trends:

(a) Increased every year, but only by a small percentage (2)

(b) Remained constant in every census from 1996 to 2011 (2)

4.1.3 It was stated that the percentage of households with five or more persons decreased from 2001 to 2011, therefore the number of households with five or more persons** decreased** by 0,060 million.

Verify, showing ALL calculations, whether this statement is CORRECT. (5)

4.2.3 The Wong Family has the following income per person:

- Mr Wong: R276 000 per year
- Mrs Wong: R541 500 per year
