A population survey, better known as a census, entails the collection of each unit in the population. In sample survey information is collected from a subset of the population. The subset, or sample, needs to be selected carefully so that it is representative of the whole population and, if that requirement is met, statistics based on the sample are good estimators for the corresponding population parameters.
A sample survey is asked of a limited group of people, while a census is conducted in an attempted to get an answer from all people in a geographical area.

difference between survey and experiment
survey is one of the techniques to conduct a research while research is the process of getting a targeted information or facts about some thing by using sample
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.
A Census is the type of survey for a complete population. A Sample Survey is only a portion of the population which is used to make predictions on the representation of the actual population.
A census aims to collect data from an entire population, while a survey gathers information from a sample of the population. Censuses are comprehensive and usually mandatory, whereas surveys are typically voluntary and sample-based. Censuses are used to provide official population counts and demographic data, while surveys are often conducted to gather specific information on a particular topic.
The population mean is the mean calculated over every member of the set of subjects being studied. It is usually not available and a survey is used to find an estimate for the population mean. The mean value of the variable in question, calculated from only the subjects included in the sample (or survey) is the sample mean. Provided some basic statistical requirements are met, the sample mean is a "good" estimate of the population mean.

difference between survey and experiment
An investigation typically involves a detailed examination or inquiry into a specific matter, often to uncover facts or establish the truth. On the other hand, a survey involves gathering and analyzing information or opinions from a group of people to better understand trends, preferences, or beliefs on a particular topic. Investigations are more focused on solving a particular problem, while surveys are generally broader in scope and aim to gather data from a sample population.

A census collects data from every member of a population, while a sample survey collects data from a subset (sample) of the population. A census provides a complete count and is more accurate, but requires more resources and time. A sample survey is faster and more cost-effective, but has a margin of error as it extrapolates findings from a smaller group to represent the larger population.
