I Percent of stars in our galaxy that belong to clusters?

    Of all the stars in our galaxy, how much of them belong to clusters?? Is our sun rare in terms of not belonging to any cluster? I can't find any sources on that

    Well, Wikipedia says "Our galaxy has about 150 globular clusters" so based on that and also its assertion that "Globular clusters, or GC, are roughly spherical groupings of from 10,000 to several million stars packed into regions of from 10 to 30 light years across." it certainly looks like they could make up a significant percentage of the stars in the Milky Way but even w/ an average of 1,000,000 stars per cluster it looks like the percentage would be in the 10% range.
