Hello. I'd like to find out more about Oklahoma.
Hi there. Oklahoma is a state located in southern region of the Central United States.
What is its population?
The population is roughly 3,751,351 people as of 2010.
Can you tell me about the state's health system?
In a 2007 study Oklahoma ranked last of all 50 states on health care performance.
Oh that is terrible! What are some health issues encountered by the state that ranked them last?
I'm afraid I don't have any further information about Oklahoma health care, but I can tell you Oklahoma also ranks low (49th) in terms of teacher pay according to the National Education Association.
Wow, it's telling how bad its education system is too. Can you tell me more about it please?
Well, I can tell you the University of Tulsa and the University of Oklahoma are both Tier 1 institutions, ranked 86th and 68th respectively.
So education quality is good, it's just that the teachers don't get paid well. What else is there to know?
The only historically black college in Oklahoma is Langston University.
Thank you for the information. YOu've been helpful.
You're most welcome!
