Latinos are participants who represent a huge portion of patients diagnosed with HIV/AIDS. The Center for Disease Control and Prevention (2015) specifies that in 2014, Hispanics accounted for 24% of diagnosed with HIV infection in the USA. 86% of that amount were men, and 14% were women. Among men, bisexuals and homosexuals accounted for 84%. This data narrows down the study population.
Gender is the first characteristic that will be taken into account when selecting the participants. The population will be divided into two parts – the assessment of men and the assessment of women. Although the percentage of women is increasingly declining. Nonetheless, this data should be empirically proved. There will be selected young males aged 18-40 years old and women aged 18-40 years. The men will be bisexuals or homosexuals since they make up an essential portion of all individuals diagnosed with HIV. For this study, I will select 200 participants (100 men and 100 women).

Since the study investigates the life of one ethnicity, I will rely on stratified random sampling strategy. I will divide all the participants into four subgroups (strata) according to their age. These will be 25 men aged 18-24, 25-29, 30-34, and 35-40. This strategy allows getting precise results. It is useful for the research since it allows to make estimation of both population and subpopulation (the Latinos in general and men of different age in particular) (“Stratified random sampling,” n. d.).

The participants will also be divided according to their financial status. There will be three subgroups: the participants from low-income families, middle-income families, and high-income families. This subdivision will allow estimating whether financial status affects the statistics. People from low-income families may make up a greater percentage of patients diagnosed with HIV/AIDS. Hence, this criterion should also be taken into account.
