Throughout many census records including the 1910 Miracode index, the code "NR" was always used to mean "Not Reported." This could be used in any column such as name, age, birthplace etc. For all other abbreviations and a better understanding of the census there are a number of sites that give that information. Here is one that is very good: http://www.censusmicrofilm.com/intro.htm I could not find a mention in any listing of abbreviations for "NR" but a call to the local census office and a few mentions on other sites confirmed the meaning behind "NR" to in fact mean "Not Reported." It does not mean "Non-Resident" as someone had suggested. My mother was not quite one year old in the 1910 census and is the only child in her parents household to be listed as "NR" for age. She was obviously a resident and in looking at many other 1910 pages, have not seen anyone listed as anything other than a whole number for their age. They probably did this to cut down on errors. Depending on someone's handwriting, "10m" could look like "10y" so to use "NR" for anyone aged less than 1 year would be very prudent on their part. No one listed in years is accurate to a month so why should a child be any different. Hope this helps clear up the confusion.
