Could you explain the difference between the 'not staying home' and 'population who are traveling'.

Is this only for trips where you immediately return home (like day trips)?

Vice the 'traveling population' which sound like a trip to a destination where you stay for days before returning home?

The full explanation for the dataset is here: US DOT link

The dataset breaks it down into "Population Staying at Home" and "Population Not Staying at Home" by day, so the "Population Staying at Home" is the difference of the Total US Population (~326M) and the "Population Not Staying at Home", or the population who take at least a trip in a day.

The paragraph that defines a trip is:

>Trips are defined as movements that include a stay of longer than 10 minutes at an anonymized location away from home. Home locations are imputed on a weekly basis. A movement with multiple stays of longer than 10 minutes before returning home is counted as multiple trips. Trips capture travel by all modes of transportation. including driving, rail, transit, and air.
