Not all forms of color blindness are hereditary. There are three distinct types of hereditary color blindness, each with different frequencies in the human population, and with distinct genetic causes. Red-green color blindness is more common among males than females, but blue-yellow color blindness is not. Talking about color blindness in general, there is no reliable ratio of male-to-female prevalence.

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.
Statistics: Survey of an entire population, as opposed to a sample survey.

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.
