In 1996,
polls taken immediately after the Presidential election revealed that 58% of people claimed they had voted, when in reality only 49% actually did. This is called the Halo Effect. People tend to over-inflate their participation in activities that create acceptability within their social group.
For many decades, pollsters such as Gallup and Barna have reported that around 45% of Americans attend church every Sunday. But there is a religious Halo Effect. Actual attendance counts have shown that the percentage of people attending church on any given weekend is much lower than was previously thought.

The Intent
of this presentation is to answer and then expand on two key questions:
“How Many People Really Attend Church in Delaware Every Week?”
“Is the Christian Church Going Forwards or Backwards in Influence in Delaware?”
As the data is analyzed county by county assessing a number of factors, a comprehensive picture of the State of the Church in Delaware will begin to take shape.

This study
uses weekend church attendance as a more reliable and more immediate snapshot of Christian influence than membership. The following map shows the percentage of the population attending a Christian church on any given weekend in all 50 states in Delaware has an average church attendance percentage (16.0%) lower than the national average (18.7%).

The Next Graph
shows the attendance numbers for the churches in Delaware in 1990 and Evangelical churches, Mainline churches and Catholic churches have all grown. Unfortunately, as overall worship attendance has declined, the population has grown. A more reliable standard for evaluating increasing or declining influence is the percentage of the population attending church on any given weekend, shown in the second graph. The only group to keep up with population growth were the Catholics.

37. The State of the Church in Delaware . . .
Because of strong population growth in Delaware, the church has both great opportunities and great challenges.
Church attendance has grown for all groups numerically, but the percentage of the population in attendance only grew for the Catholic churches.
The percentage of the population attending church has decreased, resulting in a 4% loss in the state-wide percentage of the population that attended church between 1990 and 2000.
A major factor in the overall decline is the insufficient net gain in the number of churches in Delaware. Ninety-eight additional churches needed to have been started in the previous decade to compensate for the decline in percentage attendance.

39. Information on the Information
The spiritual health of churches is multifaceted, and is obviously much more complex than an attendance trend can portray. However, following the example of St. Luke in the Book of Acts, who used the number of people who showed up at various events as a sign documenting the health and growth of the early church, I would suggest that attendance is the single most helpful indicator of health, growth and decline.
Information has been compiled only for orthodox Christian groups – Protestant, Catholic and Orthodox. The Mormons, Jehovah Witnesses, Unitarian-Universalists and the International Churches of Christ have not been included. In addition, information about non-Christian groups has not been compiled.
African American denominations publish very little that is statistical – often not even a list of current churches. This study used data from the 1990 Glenmary study on Black Baptist estimates and AME Zion churches, the average African American worship attendance (from the Barna Research Group), and a statistical model based on the population of African Americans in each county in 1990 and These were combined to come up with as accurate an estimate as possible.
Independent church data is almost impossible to obtain. (There are actually fewer totally independent churches than is assumed. Most are part of some voluntary association, which typically keeps some records.) Data from the 1990 & 2000 Glenmary study on larger Independent churches (limited to over 300 in attendance) was used along with a statistical model to estimate the attendance at smaller independent churches.
In Catholic churches, the definition of what constitutes membership varies with diocese and church, making numbers sometimes inconsistent from state to state and county to county. In addition to actual mass counts from 1/3rd of Catholic parishes, membership information has been merged with attendance patterns from similar dioceses based on the size of the diocese and the region in which it is located.
Orthodox Churches are included in Totals, but not included as a separate group because of smallness of size nationwide. Division into Evangelical and Mainline categories is based on the division by the Glenmary Study.
This study only looks at how many people attend a Christian church on any given Sunday. The term ‘regular attender’ can be designated to mean someone who attends a Christian church on a consistent basis. Using a simple definition for ‘regular attender’ (attends at least 3 out of every 8 Sundays), between 23% and 25% of Americans would fit this category. Adding ‘regular attenders’ of non-orthodox christian churches and other religions to the totals would increase the percentage to 26% – 28%.

This Presentation
is based on a nationwide study of American church attendance, as reported by churches and denominations. The database currently has average worship attendances for each of the last 10 years for over 170,000 individual churches.
It also uses supplementary information (actual membership numbers correlated with accurate membership to attendance ratios) to project the attendances of all other denominational and independent churches. All told, accurate information is provided for all 300,000 orthodox Christian churches.1
1 This presentation looks only at people attending orthodox Christian churches. Approximately 3 million people attend non-orthodox Christian churches, and perhaps 3 million attend a religious service of another religion. Those ‘houses of worship’ would add another 35,000 churches in the United States and increase the 2000 percentage to 20.5%.
