Question 1:

What was the annual incidence rate of Aids per 100,000 populations of Hispanics?

The annual incident rate of Aids is the number of new cases of AIDS in the population of

Hispanic, the following information is provided:

-New cases of AIDS reported in Hispanics in 1991: 95

-Hispanic population in 1991: 452,780

The incidence rate per 100000 of the population is calculated as follows:

Incidence rate = [new cases of the disease/ total population size] X 100000

Therefore we substitute the values as follows:

Annual incidence rate of Aids per 100,000 = (95/452780) X 100000 = 20.98149

Incidence rate = 20.98149

Demography and Health

This means that there were 20.98 new incidences of Aids per 100,000 populations of Hispanics.

Question 2:

What is the prevalence rate of Aids per 100,000 populations of Hispanics?

The prevalence rate of aids per 100,000 population of Hispanics can be defined as the number of people who have AIDS as at 1991. The following information is provided:

-Cases of AIDS in Hispanics reported from 1981- 1990: 850

-New cases of AIDS in 1991: 95

-Hispanic population in 1991: 452,780

The prevalence rate per 100000 of the population is calculated as follows:

Prevalence rate = [individuals with the disease-deaths associated with the disease/ total population size] X 100000

Demography and Health

Therefore we substitute the values as follows:

The prevalence rate of aids per 100,000 = [(850+95-595)/452780] X 100000 = 77.30023

Prevalence rate of aids per 100,000 population of Hispanics=77.30023

Question 3:

Identify the causes of death that are among the top ten in one ethnic group, but not in one or both of the others.

One of the major causes of death among the ethnic groups that is only in one category is suicide; suicide among the white non Hispanic is one of the top ten causes of disease that is not included in the other categories.

Question 4:

Demography and Health

Seven diseases that cause death among the three ethnic groups are similar in all groups and they include Diabetes mellitus, Cerebrovascular disease, HIV, Pneumonia and influenza, Accidents, heart Diseases and Malignant neoplasm, all these seven diseases are included in all the categories as top ten causes of death. Only a few differences exist where white non Hispanic groups has suicide as one of the top ten causes of death, and another difference is that Homicide and legal intervention is not a top ten cause of death among the white non Hispanic.

Question 5:

In which Hispanic subgroup is the neonatal mortality risk the highest

Hispanic subgroups include Mexicans, Puerto Ricans and Cubans, the subgroup with the highest neonatal mortality risk is the Puerto Ricans group with a total high of 7.9.

Question 6:

In which group is the post-neonatal mortality risk the highest:

The group with the highest post neonatal mortality risk is the blacks, the blacks have a total high of 6.3, while the Cubans have the lowest post neonatal mortality risk which is 2.0.
