The number of registered nurses needed in the US by the year 2030 is estimated to skyrocket 28.4%, to 3.6 million, according to research released by RegisteredNursing.org. While most states are projected to keep up with demand, many places are expected to have significant shortages in registered nurses.

California tops the list with an estimated 44,500 deficit in registered nurses, nearly three times the projected deficit in the next-shortest state. Texas, New Jersey and South Carolina will lack more than 10,000 RNs; Alaska, Georgia and South Dakota will each be short several thousand.

On the flip side, Florida will have too many RNs, with a projected overage of 53,700 nurses. Ohio comes close with 49,100 more registered nurses than it will need. Virginia, New York, Missouri and North Carolina are estimated to have more than 15,000 extra RNs.

The report also found Hawaii and California pay RNs more than any other state, with median wages totaling more than $100,000. Higher cost of living and growth contribute to high wages in western states, with Oregon, Alaska and Nevada following with wages between $85,000 and $90,000. Southern and Midwestern states tend to pay less, partly as a function of cost of living. Despite facing an oncoming RN shortage, South Dakota offers the lowest annual median pay at $55,660, alongside Alabama, Iowa and Mississippi.
