My understanding is that Esperanto's vocabulary relies primarily on Indo-European languages. Here are a few of the major families within that group:

• Italic
• Germanic
• Balto-Salvic
• Hellenic

At a high level, do we have estimates of the percentage of Esperanto vocabulary that comes from each of these families? What percentage comes from non-IE languages?

Ideally I'd like to know about modern Esperanto's vocabulary, not just what Zamenhof used.
