1. A census counts each person at the place where they were present on census night. What kind of census is this?

  1. De jure
  2. Post-enumeration
  3. Register-based
  4. De facto
Answer and working

D. De facto

A de facto census counts people where they are at the census moment; a de jure census counts them at their usual residence.

2. The Laspeyres price index weights the prices of each period by which quantities?

  1. Current-period quantities
  2. The average of base and current quantities
  3. Quantities of the period with the highest value
  4. Base-period quantities
Answer and working

D. Base-period quantities

Laspeyres = sum p1 q0 / sum p0 q0 x 100: it prices the base-period basket at current prices. Current quantities give Paasche, and the average of the two gives Marshall-Edgeworth.

3. Death rates per 1,000 are 5 (under 50) and 20 (50 and over) in district A. A standard population has 70,000 under 50 and 30,000 aged 50 and over. What is A's directly standardised death rate?

  1. 12.5 per 1,000
  2. 25.0 per 1,000
  3. 9.5 per 1,000
  4. 15.5 per 1,000
Answer and working

C. 9.5 per 1,000

SDR = (5 × 70,000 + 20 × 30,000)/100,000 = 9.5 per 1,000. 12.5 is the unweighted average of the two rates.

4. Output rises by 25% in one year and falls by 20% the next. What is the compound annual growth over the two years?

  1. 0.0%
  2. 2.5%
  3. 5.0%
  4. -2.5%
Answer and working

A. 0.0%

1.25 x 0.80 = 1.00, so output is unchanged and the compound rate is zero. 2.5% is the arithmetic average of +25 and -20, which overstates growth.

5. Why are international migration statistics among the least comparable demographic data across countries?

  1. Migration is counted only by the United Nations
  2. Migration is counted only by the United Nations, not by national statistical offices
  3. Migrants are always counted twice in national censuses, once at each end of the move
  4. Countries define migrants with different minimum durations and boundaries
Answer and working

D. Countries define migrants with different minimum durations and boundaries

The UN recommends one year of changed residence for long-term migrants, but national definitions and data sources (registers, border data, surveys) differ.
