Censuses make a huge variety of general statistical information about a society available to both researchers and general public. The information related to population and economic censuses can be forecasted in planning public services (education, health, transport, and funds) as well as in business (for setting up new factories, shopping malls, or banks and even marketing particular products).
To discover frequent patterns, each statistical area (for example, municipality, city, and neighborhood) corresponds to a transaction, and the collected indicators correspond to the items.
