Bay of Pigs. Kennedy didnât wait long for the first confrontation of his presidency. Only weeks after he took office he was told of a secret CIA plan to send an army of Cuban exiles to overthrow Fidel Castro and rid the western hemisphere of its first Communist regime.
An enumeration district, as used by the Bureau of the Census, was an area that could be covered by a single enumerator (census taker) in one census period. Enumeration districts varied in size from several city blocks in densely populated urban areas to an entire county in sparsely populated rural areas. Enumeration district maps show the boundaries and the numbers of the census enumeration districts, which were established to help administer and control data collection.
14.6 Duration of enumeration refers to the time taken to conduct the census enumeration. In the case of a population census de facto, the entire operation is ideally completed in one day, at least in urban areas, and in just a few days in rural areas. This is not possible in the case of an agricultural census.
