Tech and finance in the Forbes 2013 billionaire list

Summary: A rough breakdown of the 2013 Forbes billionaire list members classified to the technology and finance sectors, in terms of numbers, total wealth, and age. While finance-related billionaires outnumber tech billionaires substantially, the advantage is much less in terms of total wealth. Tech is better represented among American and especially among younger billionaires. Many disclaimers apply, and data on these extremes should not be given excessive weight in evaluating the expected financial returns of careers, which are primarily driven by much less extreme outcomes, and must be adjusted for human capital and population.
