1Vital statistics primarily deals with numerical facts about which of the following?
A.Vital events in a human population such as births, deaths, marriages, and migration
B.Only the market prices of consumer goods over time
C.Quality variation of manufactured industrial products
D.Optimal allocation of scarce resources in operations research
Explanation: Vital statistics (demographic statistics) analyses and interprets numerical data on vital events in human populations—births, deaths, marriages, migration, and related rates used in demography and public health.
2In a closed population (no migration), if P₀ = 100,000, live births B = 1,850 and deaths D = 1,680 in a year, what is the population at the end of the year Pₜ?
A.100,170
B.98,150
C.101,850
D.101,680
Explanation: For a closed population, Pₜ = P₀ + (B − D) = 100,000 + (1,850 − 1,680) = 100,000 + 170 = 100,170.
3In a town, mid-year population was 150,000 and live births during the year were 6,000. The crude birth rate (CBR) per 1,000 is:
A.40
B.25
C.4
D.60
Explanation: CBR = (Number of live births in the year / Mid-year population) × 1,000 = (6,000 / 150,000) × 1,000 = 40.
4If mid-year population is 80,000 and deaths in the year are 960, the crude death rate (CDR) per 1,000 is:
A.12
B.1.2
C.120
D.8
Explanation: CDR = (Deaths / Mid-year population) × 1,000 = (960 / 80,000) × 1,000 = 12.
5Age-specific death rate (ASDR) for an age group is defined as:
A.(Number of deaths in the age group / Mid-year population of that age group) × 1,000
B.(Total deaths in the population / Mid-year population of that age group) × 1,000
C.(Number of deaths in the age group / Total population of all ages) × 1,000
D.(Infant deaths under 1 year / Live births) × 1,000
Explanation: ASDR for an age class uses deaths and mid-year population both restricted to that age group, usually per 1,000.
6In a community there were 6,500 live births in a year and 350 infant deaths (under 1 year). The infant mortality rate (IMR) per 1,000 live births is:
A.53.85 (approx.)
B.18.57
C.350
D.5.38
Explanation: IMR = (Infant deaths under 1 year / Live births in the year) × 1,000 = (350 / 6,500) × 1,000 ≈ 53.85.
7Neonatal mortality rate (NMR) uses which numerator?
A.Deaths of infants within the first 28 days (about one month) of life
B.Deaths of mothers due to childbirth
C.Deaths of all persons under 5 years
D.Stillbirths only
Explanation: NMR is based on neonatal deaths—commonly defined as deaths within the first 28 days (about one month) of life—per 1,000 live births.
8Quinquennial age-specific fertility rates for women of child-bearing age are 25, 60, 70, 40, 20, 12 and 5 (per 1,000). The total fertility rate (TFR) computed as 5 × Σ ASFR is:
A.1,160
B.232
C.116
D.580
Explanation: For 5-year age groups, TFR = 5 × Σ(ASFRs) = 5 × (25+60+70+40+20+12+5) = 5 × 232 = 1,160 (per 1,000 women; often reported as 1.16 children per woman when scaled).
9Which statement correctly distinguishes GRR from NRR?
A.GRR ignores female mortality between birth and end of reproductive life, while NRR adjusts for survival of daughters
B.NRR is always larger than GRR
C.GRR uses male births only, NRR uses female births only
D.Both GRR and NRR are mortality rates, not fertility growth rates
Explanation: Gross reproduction rate (GRR) is based on female births without fully adjusting for mortality of potential mothers through reproductive ages; net reproduction rate (NRR) incorporates survival, so NRR ≤ GRR.
10Given P₀ = 126,305; births B = 24,500; deaths D = 4,050; immigrants I = 8,065; emigrants E = 6,000. The population at the end of the period Pₜ is:
A.148,820
B.142,755
C.154,820
D.134,820
Explanation: Pₜ = P₀ + (B − D) + (I − E) = 126,305 + (24,500 − 4,050) + (8,065 − 6,000) = 126,305 + 20,450 + 2,065 = 148,820.
