The response from the hearings and the meetings were reviewed by eight preparatory committees which produced working papers and recommendations to be presented at the Call to Action conference held in the Detroit convention center with 1,340 delegates in attendance, 152 of which were appointed by bishops of the 167 American dioceses. Each of 92 national Catholic organizations were allowed to send a single delegate to represent them. Almost a third of all delegates were clergy (mostly priests with 110 bishops), another third were women. Half of all the delegates were church employees. The delegates broke into small groups using the working papers as a basis of discussion but free to make their own recommendations to the NCCB/USCC.
