The population of a city on February 15, 2005, was 36,600. The city has a passive

• 20 per 1,000 population

The following table gives the mean annual age-specific mortality rates from measles during

In a country with a population of 16 million people, 175,000 deaths occurred during the year
ending December 31, 2005. These included 45,000 deaths from tuberculosis (TB) in
