This research aims to identify the most contributory factors of married women currently using contraceptives as family planning in Nigeria by factor analysis and cluster analysis techniques and then compare the results to get the most important variables. Data was a secondary data extracted from National Population Commission. In the practical section, principal Component method in factor analysis and Ward’s Hierarchical method in cluster analysis were used to determine the most influential variables in the use of modern contraceptives among married women migration. From this study, it was reached that there are similarities of the variables extracted in factor analysis and cluster analysis, that is, the number of cluster equals the number of factors, as well as the sequence of variables within the factors are the same sequence of variables in the clusters except the factor and cluster (four and five) there are an exchange in place of variables, and it was the most important influencing variables are any method, any modern method, withdrawal, periodic abstinence, male condom, injectable and IUD.
