In terms of how it affects people, it would be a matter of
interpretation around this aspect:
Does the addition of the headers make the content easier to understand?
(In some cases it is more clear cut - it would be impossible to
understand without headers.)

I guess if it were an absolute rule (it's not, its a guideline), then
any data table should have headers. A data table is defined as:
"When tables are used to represent logical relationships among data --
text, numbers, images, etc., that information is called "tabular
information" and the tables are called 'data tables'."
http://www.w3.org/TR/WAI-WEBCONTENT/#tabular-information

Each row/column has a relationship (e.g. the last column is the state),
so I would say yes, it should have headers.

It's a judgment call, personally, I tend to side with maximum ease of 
use and would add the headers. I wouldn't make the assumption that 
everyone else will understand so easily.

Hth,
