Below is a chart that lists statistics for Ferguson and St. Louis county so that readers can see how Ferguson compares to its surroundings. (click on the chart to enlarge)
As noted in the news, Ferguson residents are primarily black, much more than St. Louis county as a whole. Residents of Ferguson are also poorer, less educated, and more likely to be unemployed on average than the county as a whole. Ferguson is a slightly younger city. Ferguson residents also have a lower home-ownership rate than the county, though it is not much lower than the national average of approximately 65%.
Many economists, including Thomas Sowell and Walter Williams (see here, here, and here), often point out that the unemployment rate for black youth is much higher than that for white youth and the statistics here support that. The unemployment rate for people aged 16 - 24 is 35.24% in Ferguson, which is primarily black, and only 23.08% in St. Louis county, which is primarily white. Employment is a good way for young people to learn about responsibility, how to interact with others, punctuality, etc.
Michael Brown, the person who was shot and killed, was 18. I am not sure if he was employed or not, but based on these statistics I would not be surprised if he was not. I am not taking a stance on the justification of the shooting until all of the facts are out, but I feel confident in saying that if there were more job opportunities for youth in Ferguson, MO then the chances of a deadly interaction between teenagers and police would decrease simply because time is scarce and people at work are not walking in the middle of the street. It is my opinion based on my experiences that idle youth of any skin color tend to get in more trouble than employed youth, but this is just my observation and not intended to be a statement of causality. Regardless, the high unemployment rate of black youths and inner city youth in general is a tragedy.
Another thing worth pointing out is that even when controlling for education, which is done in the bottom most portion of the chart, Ferguson residents have lower median earnings. Median earnings of a person with a bachelor's degree in Ferguson are only $38,757 vs. $50,545 in St. Louis county. The gap is even wider for a graduate or professional degree, $51,916 vs. $67,949. Of course the type of degree earned, occupation type, and the actual ability of the individuals are not controlled for in this simple statistic, but it is still interesting in my opinion.
