* Gender - includes only two options, male or female, prob for transgendered and "two spirit" people.
* Marital Status - should LGBT families or those in domestic partnerships answer married? My gayest sources indicate no, not because they don't want their relationships recognized, but because the federal government does NOT recognize them yet, and it's a reminder that the easiest way of boosting the number of stable two-parent, dual-income families is to count the ones that already exist but aren't counted yet (and thereby recognize the unions to afford them the 1000+ federal benefits - esp. taxes - they are currently ineligible to receive).
