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

"The proportion of employed North Tahoe Truckee residents that work outside of the region has increased steadily since 2002, with far less fluctuation in response to state and national economic conditions.  For example, an estimated 37.8 percent of the employed resident population worked outside the Study Area in 2002.  This increased fairly consistently to a high of 48.5 percent in 2010, [and has been stable since].  One possible explanation for these trends is that many of the region’s out-commuters are higher-income workers who are less likely to be laid off during tough economic times.  Anecdotal evidence also suggests that many of these workers may be telecommuters who are employed in the San Francisco Bay Area and elsewhere."
