Professor and data journalist Alvin Chang has created a wonderful interactive platform, with an accompanying explainer video, showing how drastic the differences are between jobs that require standing and those where sitting is permitted.

Using a variety of parameters, Chang plotted the minor and major differences along the lines of exposure (are you outside, how hot or cold does it get, is it loud?), racial and immigrant demographics, abilities (can you take pauses, can you work remotely, do you ever need to crouch?) and other markers to determine how much flexibility jobs in the US allow.

Here are some of the things Chang observed:

• Sitting jobs have the flexibility to stand, often require a bachelor's degree and have higher incomes than their standing counterparts.
• Standing jobs lacked all of these freedoms, and instead came with more hazard and injury.
• Jobs clustered in the middle, which offered the best (and worst) of both of these worlds, included gigs like lifeguards, doctors, police officers and mail clerks.

Here are screen grabs from Chang's video (which is linked below):
