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. Three commodities have base prices 20, 10, 40, base quantities 5, 12, 3, current prices 25, 12, 44 and current quantities 4, 15, 3. What is the Paasche price index?

  1. 117.94
  2. 84.95
  3. 117.71
  4. 121.18
Answer and working

C. 117.71

sum p1 q1 = 100 + 180 + 132 = 412; sum p0 q1 = 80 + 150 + 120 = 350. P = 412/350 x 100 = 117.71. 117.94 is Laspeyres; 84.95 is the reciprocal (the index from period 1 back to 0).

3. Country A has a higher crude death rate than country B, but lower age-specific death rates at every age. What explains this?

  1. Country A has more complete birth registration
  2. Country A has an older age structure
  3. Country B has a higher infant mortality rate
  4. Country A must have a younger age structure
Answer and working

B. Country A has an older age structure

The CDR is weighted by age composition; a population with many old people has many deaths even with low age-specific rates. Standardisation removes this effect.

Demography & Vital Statistics · Measures of mortality: crude, age-specific and standardised death rates; infant mortality

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. Which equation is the demographic balancing equation?

  1. P_t = P₀ + B + D − I − O
  2. P_t = P₀ × (B/D)
  3. P_t = P₀ + I − O
  4. P_t = P₀ + B − D + I − O
Answer and working

D. P_t = P₀ + B − D + I − O

Population change equals natural increase (B − D) plus net migration (I − O).
