This document discusses population, census, and sampling. A population is all people or items with a common characteristic, while a census collects data from every member. Sampling selects a subset for analysis. A census provides accurate, reliable results but is costly and time-consuming, while sampling is faster and cheaper but less precise. Random sampling gives each member an equal chance, while non-random sampling relies on accessibility. Sampling saves resources if done strategically and can check census results, while a census offers detailed demographic information.
