I took the notes below from Peter Linehams article to Vision New Zealand on Mega Church. Some interesting analysis http://www.visionnetwork.org.nz/index.php?option=com_docman&task=cat_view&gid=22&Itemid=90

Younger but not that much younger attend

More unmarried and divorced attend

White collar or ethnic makeup

Urban

Of the 10 largest churches only 1 is Pentecostal

Our culture is very imitative of the United States

New more structured Pentecostal model is emerging

Underlying the mega church is an awareness of the shrinkage of congregations and the need for new ways to respond.

Single services in the catholic setting are very much larger than protestant services.

Mega church reflects a more commercialised society.

Mega church reflects a more mobile society.

Competitive elements

More plastic culture

In large churches people are often not involved - but don’t mind this

Members of mc are less involved outside the church 72per cent not involved compared to 65pc average church.

But higher level of evangelistic groups compared to normal church.
