According to academic Fran Markowitz, there are a number of "administrative apparatuses and public pressures that push people who might prefer to identify as flexible, multiply constituted hybrids or with one of the now unnamed minority groups into one of the three Bosniac-Croat-Serb constituent nations". These include respondents being encouraged by census interviewers to identity as belonging to one of the three constituent peoples. Her analysis of marriage registration data shows, for instance, that 67 percent of people marrying in 2003 identified as Bosniak or Muslim, which is significantly lower than the 79.6 percent census figure from 2002 (unlike the census, where people respond to an interviewer, applicants to the marriage registry fill in the form themselves).
