Regional commuting patterns collected from the Longitudinal Employer-Household Dynamics (LEHD) dataset, which is published by the Center for Economic Studies at the U.S. Census Bureau. 

The data indicates the percentage of persons employed in the Tahoe Truckee Unified School District who live outside of the area.

From the Truckee North Tahoe Workforce Housing Studay completed by Bae urban economics: 

"The data indicate that the rate of in-commuting tends to increase during times of economic growth and declines during times of economic hardship.  For example, the rate of incommuting increased steadily during the last major economic expansion, from 55.4 percent in 2002 to a peak of 61.5 percent in 2008.  Following the onset of the national recession, the proportion of in-commuters dropped to a low of 49.7 percent in 2010, likely due to improvements in housing affordability within the Study Area.  As the economy transitioned from recovery to expansion, the proportion of in-commuters began to increase, growing to 58.6 percent in 2013.
