context_page_description: The list of WTA number 1 ranked players shows the professional women's tennis players who have been or currently are ranked world No. 1 by the Women's Tennis Association, along with the dates of first reaching and losing that spot. Since the WTA began producing computerised rankings on 3 November 1975, 27 women have reached the highest singles ranking and 43 women the highest doubles ranking. The WTA rankings are a merit-based method for determining the rankings in women's tennis and the WTA releases ranking points weekly based on how players fared during the previous 52 weeks.
context_section_description: The source for the following table through the week of January 6, 2012, is the 2012 WTA Tour Official Guide, page 172.
