Why are there not many nativeamericans today?

Answer 1

Native Americans have merged into the multicultural society of the the United States and other countries. As they inter-marry and lose traditions they no longer identify themselves as native Americans.

There are a few remaining communities where native genes, traditions and culture continue, but those communities are leaking young members who move away to find jobs, partners and first world lifestyles. Eventually there will be nobody left who can claim to be pure native American.

My grandfather was native American, but he married outside the culture. My lifestyle is western. I cannot claim to be native American.
