1. sponsorship by national government 2. defined territory 3. universality - include everyone in either de jure or de facto basis 4. simultaneity - a fixed day, hour, and moment becomes the chronological dividing line for inclusion or exclusion 5. individual persons are counted, not groups 6. compilation and publication of the data must occur 7. Define periodicity - conduct the census in a year as close as possible to one ending in 0

geographic information systems
computer-based systems that allows the user to combine maps with data that refer to particular places on those maps and then analyze those data and display the results as thematic maps
historical data

vital statistics

error that occurs in sampling due to the fact that a sample is rarely identical in every way to the population from which it was drawn

usual residence
the concept of including people in the census on the basis of where they usually reside
spatial autocorrelation
the concept that everything is related to everything else, but neat things are more related than distant things
demographic balancing equation
the formula that shows that the population at time 2 is equal to the population at time 1, plus the births between time 1 and 2, minus the deaths between time 1 and 2, plus the in-migrants between time 1 and 2, minus the out-migrants between time 1 and 2
de facto population

de jure population
the people who legally "belong" in a given area whether or not they are there on census day

the situation that occurs in a census when some groups of people are more likely to be underenumerated than other groups

the use of census data to determine the number of seats in the U.S. congress that will be allocated to each state
how are vital statistics provided?
