On vacation the last two Sundays in Upstate New York, I searched for Reformed or Presbyterian Churches to attend with my family. This search shows the rough situation the state is in.
Consider this map of United Reformed Churches. There are a few heading towards populous NYC, and some in Ontario. But really none in Upstate New York.

Then there is the Orthodox Presbyterian Church. They have a few churches.

My own Bible Presbyterian Church has just two churches. Unionville where I serve, and at the other end of the State there is the Bible Presbyterian Church on Grand Island. In between, nothing.
The PCA, a denomination I have many concerns with especially in New York, has a few more churches:

The RPCNA has surprisingly more:

But all told, in a state (if we exclude NYC) of 12 million people, there are maybe 50 Reformed / Presbyterian churches.
Compare this with a representative sample down south. There are more of such churches in the Charlotte, NC area than all of New York State.

Does this mean that there is opportunity to establish a Reformed / Presbyterian church in New York? Well, Yes and mostly no. There definitely is opportunity in the sense that a church in many places of New York will not have competition. But, with the general lack of Reformed believers in New York, and the general stream of people leaving the state, it is a hard sell.
I ask that believers in other places pray for states like New York (and even more scare states like those in the Western USA).

Well, you missed the congregation that I pastor, East Palmyra CRC. We probably could be in either the URCNA or OPC. Given some of the history of the CRC (from 1924 to the 1990’s move on women in office and expulsion from NAPARC), I can understand the omission. However, I am hopeful of better things in the days ahead.
Great to hear from you Michael. I know two fairly conservative CRC churches in my area, Goshen NY and Sussex NJ.
May the Lord bless your ministry in East Palmyra.
