After the consistory on September 30, the number of electors in the College of Cardinals will increase to 137. Throughout the 10 years of Francis' pontificate, the makeup of this group of cardinals has changed a lot from the group at the conclave that elected Pope Francis in 2013.
At that time, 28 cardinal electors were Italians. After September 30, there will be 15. Despite these reduced numbers, Italy remains the country with the most cardinals with the ability to vote for the next pope.
The next country of relevance in the College of Cardinals is the United States. In 2013, it had 11 cardinals. As of Saturday, it will remain with this same number.
Spain is the third country in number of cardinal electors with 8. In 2013 it had 5. After September 30, more than 70% of the cardinals will have been appointed by Pope Francis. Including non-electors, the total number of members of the College of Cardinals will be 242.
