A neighbor came to my house today and gave me some materials about the census, including this sheet with the codes I needed to fill it out on line (I’ve blurred those numbers in the image). It wasn’t hard to fill the information out on line (they have an English interface) but they could have made it easier to find the right URL. As you can see it’s nowhere to be found on this sheet. You have to look elsewhere for it and even then you have to click through a number of screens to find what you are looking for. If you’d like to go directly to the page where you type in your information, use the following URL:
