Demographics describe the population of a research study such as age, sex, socio-economical level, education levels, employment, or disabilities (Connelly, 2013). This information helps the reader understand the population under study and why certain results may reflect populations differently. Researchers aim to have their studies reflect the general views of the entire population, but only a small sample is studied. Often the researcher will need to locate a small or uncommon population to study and compare them to the general population. Obtaining demographic data and comparing the results is necessary to portray study results. Demographic data is self-reported by the research participant. To understand the population being studied it is imperative demographic information is available, so disparities can be identified, and improvements be made (U.S. Department of Health and Human Services, 2018). If a certain population is identified as being underserved consistently, measures can be put into place to improve the quality of life or conditions for that certain population.
