On 18 September Scottish residents will have the opportunity to vote in a referendum on independence. There have been numerous surveys tracking voter attitudes to independence and the website What Scotland Thinks provides a useful resource on general trends. We know, for example, that while different polling firms tend to find varying levels of support for independence there is little movement within those firms. Likewise we know something about the type of voters who support independence. According to some polls, women and older voters are less supportive, with Scottish born and those with a strong Scottish national identity more supportive. There are, however, still unanswered questions about the sources of support for different constitutional options.
