Where is Igbo spoken?

While looking to translate a foreign language caption to an Instagram picture, I happened to see a language named Igbo in the list of options.

Having not heard of it before, I did a quick investigation.  So ... here's Igbo:

• Principal and native language of the Igbo people, who live in southeast Nigeria.

• About 27 million speakers worldwide, including some Caribbean islands and other African countries.

Here's a lot more about it, if you're interested:
