The Census reference date refers to:

The start of the enumeration period
The specific time point data refers to
The deadline for data collection
The date results are published

The correct answer is: b) The specific time point data refers to.

The Census reference date is the specific time point to which the data collected in the census refers. This is important because it allows for comparisons of data over time. For example, if the Census reference date is 2020, then the data collected in the census can be compared to data collected in previous censuses to see how the population has changed.

The other options are incorrect because:

  • a) The start of the enumeration period is the date on which the census begins.
  • c) The deadline for data collection is the date by which data must be collected.
  • d) The date results are published is the date on which the results of the census are released to the public.
