If economists are highly skilled in research and data science why is their demand going to increase by only 4000 jobs over the next decade? The skills that economists possess are crucial to businesses, governments and R&D firms so why isn't the demand for economists increasing at a rapid rate?

The increase of 4000 jobs is predicted by US bureau of labour statistics.

Sounds like this is conflating "quantity demanded" with "demand". There are not many well trained economists when looking at the entire US labor market. Are qualified economists able to find jobs? Do skilled economists receive a wage premium compared to other professions that required similar levels of training? Do many people with economics training end up being employed in unrelated jobs? These are better measures than just the number of jobs by itself, it gets at the interaction between supply and demand. 

An organization usually has to be pretty large to benefit from employing an economist. More often they contract that out to another firm, because they only have a small need for detailed economic analysis. Many small businesses (restaurants, beauty salons, specialty retail, boutique software, etc...) don't need highly skilled economic research to increase profits by a few percentage points. The margins they operate under make that a net loss after paying for the research.
