Ability to compare multiple jobs simultaneously. Make a note saying the graph will appear once you pick a job, or have it pop up by default on a default job. Center the numerical figures in their cells.

One thing I was thinking about on this note was, comparing the "true cost of post-graduate education", in other words, you choose a job that will require X years of post-grad, and then you choose a job that doesn't. And it will compare lifetime earnings.

Make the list of jobs and/or the list of categories searchable and associate search keywords to jobs. For example, if I want to find 'Professor', it seems to come under postsecondary teachers, which wouldn't have been something I would have thought of without trawling the list of educators, but I would have found it if I could search by 'Professor' and get the result returned.

Good idea.

'Actuaries', 'Statisticians', 'Mathematicians' seem to have a duplicate entries. Check database for other duplicates by querying for where job names coincide.

Good catch. From looking it seems like the BLS statistics (which is what this polls from) has duplicate entries that have the same info but separate ID codes. Government efficiency right there. I'll rewrite the script to scrub these out.

Track down the figures where you don't have data, or establish that there is not enough data, and let the user know which is the case so they know the provenance of researched or omitted figures.

What specifically did you mean here?

t. Perhaps you could have a mode like the current one and a 'wandering' mode where you start with a specific job then have it compared and linked to related or similar jobs

I think the big problem with trying to determine "related jobs" is that, more often than not, in the actual job market, the relationship between similar jobs is in name only. If I'm trying to hire someone for sales, someone who has a lot of marketing experience probably isn't going to be a great candidate, even though "sales" and "marketing" seem to go hand-in-hand.
