A census is an official count or enumeration of persons. In the hospital setting, this is the total number of patients admitted to the facility, generally exclusive of newborns. This count is typically taken at the same time each day, usually taken just before midnight. Censuses may be recorded by unit, ward, service, or the entire hospital or health care facility. This information is used, among many other purposes, to calculate an Average Daily Census, which is the average number of Patients per day in a hospital over a given period of time.
This class represents the result of the enumeration, which may be stored as a simple number, or may be comprised of pointers to the actual Encounters included in the count.

Attributes
Integer	count	This is the number of Patients that were admitted into the facility or program on the date/time upon which the Census Event took place. Note that this property is marked as derived because it might be calculated based on the number of Encounters that were active at the time of the census.
«TS» PointInTime	dateTime	The date and time at which the enumeration of Patients took place. The census is taken at regular intervals (often daily, but sometimes monthly or quarterly) at the same time of the day (usually 11:59 PM). Only those Encounters that are active (admitted) at the time the Census Event are included in the count.
AbstractDurableEncounter	includedEncounter	A census is the number of Patients that were admitted into the facility or program on the date/time upon which the Census Event took place. This may be calculated by identifying the Encounters that were active at the time of the census. This optional property points to those Encounters included in the Census. Alternatively, the CensusEvent.count property may be used to simply record the count without storing the encounters enumerated.
