A census.
The number of individuals in the population is the population's size. If a population is small enough you will be able to determine the size by counting the individuals.
A survey focused on the size and composition of a population is typically referred to as a demographic survey. It gathers data on various characteristics such as age, gender, ethnicity, marital status, education level, and household size. This information helps in understanding the distribution and trends within a population, aiding in effective policy-making and resource allocation.

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.

You can get a property survey done by hiring a licensed surveyor or a surveying company. They will measure and map the boundaries of your property to determine its size and location.
The population is every data point you intend to generalise the survey results to. The sample frame is those data points that you can pick from for the survey. The sample is which of these data points you actually survey, and the sample size is how many of those data points there are. For instance, if you have 700 students in a school, and you have access to 300 of them, and decide to give 30 of them a survey, the sample size is 30.
To conduct a survey with a sample size of 3/8, you would need to select 3 out of every 8 individuals in your population to participate in the survey. This can be done by using a random selection method or by dividing your population into groups of 8 and selecting 3 individuals from each group.
