merger with WASG, the voting base of PDS was an approximate cross-section of the population, favoured somewhat by more educated voters. Since the merger, The Left has become more favoured among working-class and poorer voters, which made up the core of WASG's support. Since the mid-2010s, the party has gained significant popularity among youth. Prior to the merger, PDS had by far the highest proportion of members over 60 years of any party, at 68%, and the lowest proportion of members under 30, at just 4%. By 2019, these numbers had fallen and risen, respectively, to 44% and 19%. The Left now has the highest proportion of members under 30 of any party. Two-thirds of members who joined the party between 2016 and 2018 were under 35 years of age. In the 2021 federal election, The Left was twice as popular among voters under 25 than among voters over 70. The PDS inherited 170,000 members from the SED in 1990, but suffered constant decline from that point until the merger with WASG. Upon its formation, The Left had 71,000 members, of which 11,500 had been WASG members. Over the next two years the party grew, reaching a peak of 78,000 in 2009, after which point numbers began to decline. In 2016, the party had 59,000 members. This trend temporarily reversed following the 2017 federal election, and the party gained several thousand new members for a total of 62,300 in 2019; however, membership shrank again to 60,350 in December 2020. Geography A large part of The Left's base and membership reside in the new states (the former GDR). The voting base of the PDS was limited almost entirely to the east; upon its formation, the vast majority of The Left's western membership came from WASG. However, the party has grown in the west in the years since: while in 2005, the Left.PDS list won just 45.5% of its votes in the western states, this grew to 57.7% in 2009, and 65.4% in 2017. Between 2016 and 2018, 72% of new party members were from the western states, 15% from the east, and 13% from Berlin. During this period, the party's membership total in the west exceeded that of the east for the first time. As of 2021, 50% of The Left's members are from the west, 37% from the east, and 13% from Berlin. Despite this, on the state level, the
