What do you do with an undergraduate degree in physics? There are job opportunities across the nation and across the economic spectrum. The Statistical Research Center of the American Institute of Physics collects and disseminates data on the physics community, including employment trends in physics, astronomy, and related fields. For a state-by-state searchable listing of many employers who have recently hired physics bachelor's into science and engineering positions, see http://www.aip.org/statistics/trends/states/state.html.
To find the latest data on what physicists do throughout the economy at different degree levels, see http://www.aip.org/statistics/trends/emptrends.html
For many other pieces of statistical information on physics, astronomy, and those trained in these disciplines, see http://www.aip.org/statistics.
