This is a paper presenting a review of the application of stringr on data,in this case data collected from a survey done on family planning. Family planning is the planning of when to have children and the use of birth control and other techniques to implement such plans. We used stringr in the data on family planning to get the number of teenagers who had participated in the survey and the number of teenagers who had similar opinions on various questions asked in the survey on family planning. Our finding was that most of the teenagers were conversant with family planning but still needed more information about it. In conclusion, we recommended that family planning should be included in the school syllabus so that the teenagers would get facts about it and help in spreading the word .
