Data about the size and composition of a population are gathered in a survey called?
A survey that gathers data about the size and composition of a population is called a demographic survey. This type of survey typically collects information on various factors such as age, gender, ethnicity, income, and education levels. The results are used for statistical analysis, policy-making, and understanding social trends.

What is the ideal sample size for a given population?
There is no "ideal" sample size for any given population, because polls and other statistical analysis forms depend on many factors, including what the survey is intended to show, who the target audience is, how much statistical error is permitted, and so on. The "Survey System" link, below, offers definitions and a couple of calculators to determine the best sample size for most purposes.

A market researcher is conducting a survey to estimate the average monthly household income in a specific neighborhood. Slovin's formula is utilized to calculate the sample size required to ensure the results are statistically significant. An environmental scientist is studying the population density of a rare species of bird in a particular habitat. By using Slovin's formula, the scientist can determine the appropriate sample size for monitoring and studying this bird population accurately.
