Final answer:
The community health nurse's data collection on education level is best described as sociodemographic characteristics, which relate to demographics and are essential for understanding health outcomes.
Step-by-step explanation:
The data collected by the community health nurse about the number and proportion of persons aged 25 or older with less than a high school education best describes sociodemographic characteristics. This type of data is related to demographic variables such as age, sex, marital status, education, employment status, and occupation which are commonly collected by governments through vital statistics and censuses. Such information is crucial in social epidemiology as it helps frame and understand health disparities and outcomes in a given population.
It is worth noting that this data does not specifically pertain to health status, which would include information on individuals' medical conditions or diseases; health risk factors which would cover behaviors or conditions that increase the risk of disease; nor health care resource consumption information, which would document the usage of health care services and supplies.
