Question

According to a national survey of asthma: On June 30, 2010, the number of residents of Florida who had been diagnosed with asthma at any time during their life was X. The population on June 30, 2010, was Y. During the same year, the number of new cases of asthma was Z. The point prevalence of asthma on June 30, 2010, using the midpoint population (population on June 30, 2010) as the denominator would be expressed asIf A equals the number of deaths in 2009 and B equals the population at the midpoint of 2009 and C equals the number of persons aged 15-24, then the crude death rate per 100,000 population would be:

Answer 1

Answer: =
`(A)/(B)` X 100,000

Step-by-step explanation:

Crude death rate is defined as the number of total deaths of persons residing in a specific area or geographical location, divided by the area's total population over a specific period, multiplied by a factor of 100,000. This is a very general estimate of a population's health over a specified period:

Total Resident Deaths= A

Total Population= B

Crude death rate: Total Resident Deaths X 100,000

Total Population

=
`(A)/(B)` X 100,000

A crude death rate typically has:

-a specific period of measurement (2009)

-a numerator: total deaths in the specified area in the given period (A)

-a denominator: this shows the total subset of the population that is at risk in the defined area from the same year (or multiple years) as the numerator- usually the mid-year estimate from the population (B)

population count estimate for the same year(s) included in the numerator. -a constant; the result of the division above is multiplied by the constant to give a whole number (seen here as 100, 000)
