Numeric
No commas
e.g. "1000" instead of "1,000"
No units of measurement
Units should be in metadata instead
Express as full number where possible
e.g. "1200000" instead of "1.2" (million)
If rounded, indicate in metadata
No rounding if possible
Give raw numbers as far as possible
If rounding is needed, try to provide at least 2 decimal places of precision
Percentages can be expressed as either a proportion out of 1 or 100.
e.g. 20% can be expressed as 20 or 0.2
The representation of percentages must be consistent throughout your dataset (e.g. among different percentage fields)
Agencies must indicate how percentages are expressed in the data dictionary
Is anything wrong, unclear, missing?
