Quality code 2 matches

By definition, both quality codes 1 and 2 mean you're sure you've found the right individual in the census, and you have evidence to prove it. If you're unsure what the criteria are to rank a match QC 1 or QC 2, please review that information in your manual.

While we love quality code 1 matches, it is not worth the extra time to find a marriage certificate or other document to bump up your quality code 2 match. You are not adding enough value to the data to warrant the extra time you must spend to find the additional documents.

If you have a quality code 3 or 4 match, then it is worth a few extra minutes (but be careful not to take too long) to see if you can find a new document to bring it up to a QC 1 or QC 2.

Quality code 3 matches are those we think are correct, but there is missing or discrepant data that makes us unsure. It's worth taking a few minutes to strengthen the match. With QC 2, you already have a strong match, so you should move on.

Death certificates

Please remember that sometimes documents have two pages. This is particularly important for death certificates. Since we are a study on health and aging, we want to collect death causes wherever possible. Always click to the next image and make sure there isn't a second page to the document. In this example, the inputter did not check for a second page, and missed multiple causes of death.
