Hi, I am aggregating monthly number_devices_residing county wise from home panel summary, also aggregating device_counts county wise from social distancing matrix. The total count in both the files are very different. I am wondering, shouldn’t the no of devices be same / similar in both matrix? Any idea what could be the reason?
