Geographic Distributions of the US Population and the School Population During the Post WW2 Era: 1950–1980America was on the move. The US Census has calculated the mean center of the US since 1790, and I Fig. 6.1 displays the trajectory of these means from 1790 to 2010. Of course, our...
To test GPS’s accuracy with individuals from populations that were not included in the reference population set, we conducted two analyses. We first repeated the previous analysis using the leave-one-out procedure at the population level. As expected, GPS accuracy decreased with 50% of worldwide...
Enter the amount of time you have spent in each place. If you leave the years, months, and days boxes blank then all of your places will be weighted equally for the calculation. As an alternative, you can use 'Other weight' to enter population or other weighting factors for each ...
states. The correlation between a state’s population and its number of Reddit users is shown in Fig. 1. We saw that the number of Reddit users per state scaled linearly with the state’s population ([Math Processing Error]β=0.99). Additionally, approximately 1.4 billion (or 35%) ...
It goes also for mobility in the sense of geographic mobility, including the migration of individuals or groups, moving from one place to another and traveling to attractive destinations in an increasingly global world (although that may not apply to the whole of the population), and not least...

1. We saw that the number of Reddit users per state scaled linearly with the state’s population (β=0.99). Additionally, approximately 1.4 billion (or 35%) comments on Reddit can be mapped to a user in one of the 50 U.S. states. From these 1.4B comments, we identified a total of...
of outcomes and has more power than standard mean comparison tests. Finally, our results are robust to using different polynomials of the running variable, and to including a rich set of relevant covariates, such as population, socio-economic indicators, and past realizations of the outcome ...
The number of ranger stations was the only factor correlating with its population abundance. Moreover, extirpation and range loss mostly occurred in the periphery of its Iranian distribution, and we detected five stepping stone areas in the center of the range. Our study suggests that under ...
