That number is an 11 percent increase in one year and up 22 percent from 2014.
"That's a humongous increase for over two years; it's just really tragic," said Kara Macek of the Governors Highway Safety Administration.
The study ranked Missouri 20th per capita in pedestrian deaths and Kansas 37th.
While Missouri's rate is higher, the numbers show a 16 percent decline in the Show Me State from 43 to 36 deaths for the first six months of 2016 compared to 2015.
Kansas in that same time period had a 54.5 percent increase from 11 deaths to 17.
Experts say the reasons for the spike include more cars on the road thanks to a growing economy and lower gas prices.
More people walking for their health and the environment is also noted as a factor.
Additionally, experts say there are more distracted pedestrians and drivers because of increased smart phone use.
On a grey, drizzly day at Kansas City's Country Club Plaza, the 41 Action News Investigators had no trouble finding drivers talking on their cellphones while driving as well as several pedestrians with their smart phones out.
"People need to not be looking at their phones all the time. They need to be aware of their surroundings," said Assistant Chief Jeff Levy of the Lauderhill, Florida Fire Department.
Traffic engineers are designing solutions.
They include fences in medians to cut down on jay-walking, traffic circles to make drivers slow down instead of stop signs they may miss, and speed bumps to force drivers to slow down.
The study shows people are much more likely to be hit at night than during the day.
It also shows alcohol was found to be a factor with either the driver or pedestrian in more than a third of the deadly crashes.
