Unfortunately the Constituency Commission seem to increasingly prefer 3-seaters these days.
The most recent Constituency Commission (whose plan hasn't been used in an election yet) reduced the number of both 3-seaters and 5-seaters by 1, increasing the number of 4-seaters by 2. But there will still be 5 more 3-seaters than there were before the 2002 election, and the number of constituencies will still be at the largest ever.
A smaller percentage of TDs represent 3-seaters (and 3- or 4-seaters) now than in the pre-Constituency Commission era going back to the 1937 elections before which there were constituencies electing more than 5 members, although things are only marginally better now than they were for most of the 60s under the 1961 plan.
