I doubt that they go door to door as much as they used to. I've lived at my current address for 15 years and the JWs have never came to my door and talked with me or my. Granted I might have missed them before 2009 the year I retired because I was at work during the week.
Several years ago the JWs did leave a tract in our door, as we were out when they stopped by. But we've never had a JW call on us in person. We don't live way out in the country, in fact there are four KHs within a ten mile radius of our house, with ten congregations.
