Heb. 10:25 ~ Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching.
In late 2012 The PEW Research Center set forth information regarding church attendance in the United States that suggested that approximately 79 % of Americans claimed that they identified with an "organized" church or religious group, while 45% said they attended service regularly. Quite naturally this lead to the conclusion that most folk, which identify with organized religion, were also church attendees.
In an October 2012 NPR report, science correspondent Shankar Vedantam, took a look at the data and the assumptions drawn from the PEW report. What he found was that there was a difference between what people "say" about their religion and organizations of faith than what they actually do regarding their faith. More specifically, Mr. Vedantam, pointed out that questions regarding religious affiliation usually shift from what one actually does by way of attendance and physical support, toward what one "feels" about their preferred group. In other words, most people feel strongly and have a preferred group of faith, but at the same time, not everyone attends or supports their preferred group with their presence.
The Time Diary Method
Columbo: Surely, that wasn't you at the golf course because you were at church the the morning of July 15th 2012 at 11:00 AM...Right?
The "time diary method" is a method of questioning that asks individuals to recount their exact whereabouts at a particular time and moment. Similar to how Detective Columbo (Peter Faulk- for those of us who still remember his screen genius) in a seemingly dumbfounded moment, asked the last question while exiting, to let the criminal affirm what he already knew. In this case, the "time diary method" allowed those that say they support a church an opportunity to expose themselves to through their own actions by following when and how often they actually attended a service with their personal presence.
This difference in Vendatam's questioning led to the conclusion that on average, only about 24% of all of them that say that they support a certain faith were actually in attendance or physically in support of their church the previous week. In other words some are saying that they believe or in this case, have a church, but are not regular attendees.
