The Conseil National des Evangéliques de France have taken on board the old target (shared by France Mission and lots of others) of seeing a church for every 10 000 people in France, hoping to give every person a reasonable chance of hearing the gospel in an intelligible way at least once during their lifetime.
For us to reach this target we need LOTS more churches. For example in Pessac alone there are currently two evangelical churches for a population of about 60 000. That means four more churches are needed. And Pessac is pretty well off, really. Neighbouring town Talence is much less reached.
For them as reads French this website tells you a bit more - http://www.1pour10000.fr/ - including a very useful interactive map ("La Carte").
