Erratum.

In issue 8(5) of JPAH, in Tudor-Locke C, Johnson WD, & Katzmarzyk PT, U.S. Population Profile of Time-Stamped Accelerometer Outputs: Impact of Wear Time ( https://dx.doi.org/jpah.8.8.1175 ), the publisher incor-rectly placed Figures 1 & 2. The image that appears with the Figure 1 caption should appear with the Figure 2 caption; likewise, the image that appears with the Figure 2 caption should appear with the Figure 1 caption. The publisher regrets this error and encourages readers to view the correct placement of each Figure in the version of the article published online.
