1. In 2008, a village encountered 1000 deaths where 600 were males and 1000 females. The
total population of that village in mid 2008 was 30, 000 were 16, 000 were males and 14, 000
females. During the same year, out of 200 cases of bird flu, 81 people died. Use the above
information to calculate the following
a) The crude death rate (CDR) for village B in 2008 is calculated using the following formulae
CDR=
∑ of deaths¿ residents ∈a given geographical location ¿
Total population for the same geograpgical location
× 1000
Total no. Of deaths = 1000+81= 1081
Total population= 30, 000
CDR= 1081
30,000 × 1000
=36.03
b) Case fatality rate of bird flu in 2008 per 1000
CFR=
No . of deaths¿ a specified disease
a defined population ¿
No . of indiv . diagnosed with the disease∈that month
×100
= 81
200 ×100
= 40.5
c) Proportionate mortality rate of bird flu in the village in 2008
PMR=
No . of deaths within a populationdue ¿ a given disease ¿
Total no . of deaths∈a population∈a time period eg a year
× 100
No. Of deaths due to bird flu= 81
Total no. Of deaths= 1081
81
1081 ×100
