What this means for you

What this means for you: a basket priced at 100 on the national baseline is indexed at 83.5 in Oklahoma. A salary that buys that basket at the baseline would need about 83.5% of that salary to buy the same basket here. That is index math from this snapshot, not a tax-equalized offer and not your rent.
