The United Nations defines the essential features of population and housing censuses as "individual enumeration, universality within a defined territory, simultaneity and defined periodicity", and recommends that population censuses be taken at least every 10 years. United Nations recommendations also cover census topics to be collected, official definitions, classifications and other useful information to co-ordinate international practice. - A school is an institution designed to provide learning spaces and learning environments for the teaching of students (or "pupils") under the direction of teachers.
