The CEB or the Census Enumeration Blocks are the most elementary census aggregates. Every national census unit has such an elementary census frame (for example, they are called "census precincts" in the United States and "first units" in some EU nations). Households are numbered serially within a CEB, and each CEB in urban India contains around 125 households or about 625 individuals.
