If you are interested in the productivity of the United States, state by state and ranked from best to worst, you can access Business Insider's website. However, the short answer to your question is probably Mississippi. Productivity is usually expressed as a ratio such as an average total output of goods divided by the total input of abour or raw materials.
Mississippi does very poorly in this respect and has a high percentage of people at or below the poverty line. Despite having good and active governors in Jackson, insufficient appears to be allocated to education and educators so that skills are better generated in order to boost productiveness.
If you define productive by how much the people living in a state contribute to its economy, than Mississippi is the least productive state in the United States. It’s not surprising to see Mississippi ranked last because it also “ranks last as the worst state for kids, has the most residents living in poverty, and has one of the poorest education systems in the country.” This ranking was developed by TheStreet.com.
They analyzed 2008 data (the most recent available) from both the Bureau of Economic Analysis and the Bureau of Labor. When they factored in the “total number of residents living in each state who were 16 or older that year, as well as the average number of hours they worked per week”, Mississippi came out at the bottom.
