The NSIDC page Springtime in the Artic (5/3/2022) has a section on sea ice age.
At the end of last summer, the extent of the oldest ice (greater than 4 years old) tied with 2012 for the lowest in the satellite record. This spring, we continue to see a dominance of first-year ice (Figure 4). The percentage of the greater than 4-year-old ice, which once comprised over 30 percent of the Arctic Ocean, now makes up only 3.1 percent of the ice cover.
The page has other graphs and maps related to ice. There is a link in the citations for data related to the graph copied here.
