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

A population has 2,600 live births in a year and 24,000 women aged 15-49 at mid-year. What is the general fertility rate?
B. 108.3 per 1,000 women
GFR = 2,600/24,000 × 1,000 = 108.3 per 1,000 women aged 15-49. 26.0 would use a total population of 100,000 (that is the CBR).

In a year there are 4,000 live births and 180 deaths of infants under one year. What is the infant mortality rate?
A. 45 per 1,000 live births
IMR = 180/4,000 × 1,000 = 45. The denominator is live births, not the infant population.

How is the maternal mortality ratio expressed?
D. Maternal deaths per 100,000 live births
The maternal mortality ratio uses live births as the denominator and is expressed per 100,000; the maternal mortality rate uses women of reproductive age.

In a life table, l₆₀ = 80,000 and T₆₀ = 1,600,000. What is the expectation of life at age 60?
B. 20 years
e₆₀ = T₆₀/l₆₀ = 1,600,000/80,000 = 20 years.

In a cohort-component projection, 50,000 women aged 20-24 have a five-year survival ratio ₅L₂₅/₅L₂₀ = 0.98 and no migration is assumed. How many will be aged 25-29 five years later?
B. 49,000
50,000 × 0.98 = 49,000. 1,000 is the number expected to die.

A projected population is 30% aged 0-14, 62% aged 15-64 and 8% aged 65 and over. What is the total dependency ratio?
D. 61.3
Total dependency = (30 + 8)/62 × 100 = 61.3 dependants per 100 working-age persons. 38.0 is the dependants' share of the total population; 48.4 is the youth dependency ratio alone.

Which conditions define a stationary population?
D. Constant and equal births and deaths, no migration, constant death rates
A stationary population is a stable population with zero growth; its age structure is the life-table Lₓ column.
