How would someone best describe the change over time in the "founding Era" (1763-1815)?Trying to get all aspects of the change in that Era such...

So are you looking for one way to describe changes in all
those areas?

Overall, I would say that the word
"democratization" might be the best one to describe the overall changes.  The word
certainly does not cover all the areas you mention (for example, it doesn't describe
economic change much and it doesn't apply much to racial minorities) but overall it does
kind of fit.

The word "democratization" at least applies to
government structures, class structures and voting rights.  The government under the
Constitution was without doubt more democratic, and voting rights were more widely given
than they had been in colonial times.  Class became much less of an issue during this
time, especially as you get later in this era and the Democratic-Republicans come to
power.

I can't think of any other word or idea that can
describe more of what happened in this era, even if my choice does not cover everything
that was going on.
