The two most popular pop-psych personality frameworks are the Myers-Briggs and Enneagram personality types. They both describe general personality so they are expected to have overlap and a common question is, what types from one correspond to what types from the other?
The largest analysis on this topic so far seems to be by an individual known as Highlander of 4,702 profiles on the Typology Central forums where users could set their type identities in their profile.
I have a much larger dataset that I should share. The data is from my what character are you test where users who took the optional survey were asked to identify their Myers-Briggs and Enneagram types if they knew them. 126,801 people provided both.
Type table below shows the number of occurrences of each type combination in the dataset.

These raw counts are hard to interpret. You can see that some types are much more common than others. The table shows what percent of each Myers-Briggs type identify as each Enneagram type (so a row adds up to 100%).

Looking at this table, we see that any type can be any other type, but there are correlations. This correspondence table seems reasonable:
