actually I had better explain abit more about census enumerators routes.
When you look at the actual census returns , you are looking at a full return for a particular registration district, lets say for example Wigan Town centre. Within each district, for practical reasons, the whole district is divided into sub-districts, each time you look at a district, you get a title page, a statistics page and then a written explanation of the enumerators route street by street, or in the case of a rural area, farm by farm. This can be looked at in all returns from 1841 to 1901 and a really good picture of the development of a place worked out.
