I've only got 2 punctures since i started cycling again 2 years ago.
One was because the rim tape was not installed properly and one of the spokes punched a little hole in the inner tube.
The second puncture was on my MTB riding after a hedge cutter has done it's job. Not a very good idea.

Approx once per 500 to 1000 miles.

The worst areas are
pavements - I don't ride on them unless really necessary
the edges of roads - I try to ride a bit further out
farm tracks - as mentioned earlier - I've had two punctures from shards of flint, once from a farm track, once on a road, near a farm track - depends if you live in an area with flints!

I have cycled the length of this country a few times, and never had a puncture.
I don't get them.
Never.

I can't remember the last time that I had a puncture that sopped me riding. Perhaps I can - 1986?. I had to walk the last 4 or 5 miles home. Other than that, I've had pinch-punctures when I've hit a sharp stone or edge on the sidewall, and needed to fit a new tube, and once or twice I've nicked the tube when fitting a new tyre, but that's all. Honest.

Since using 23mm instead of 20mm, pinch punctures have gone.
No perforations by thorns, glass, nails, pins, foreign objects - nowt.

Buy decent tyres ....... and ride on the road.

Hardly ever. Probably one every 3 - 5000 miles. However, when I do get one I almost always end up getting another on the same ride. I guess this is because after repairing the first puncture, or changing the tube out on the road, I can only manage to pump my tyres up to about 60psi with my mini pump, and tyres of this softness don't seem to resist sharp objects very well. When my tyres are pumped up rock hard - 120psi - I often hear road debris shoot out from under my tyres and hit bus shelters, street furniture, shop fronts etc. When my tyres are soft I don't hear this. I suppose the greater contact area of the softer tyre effectively envelopes the road debris and allows it to cut its way through. I should add that this is on my road bike with 23mm tyres. When I used to have a mountain bike with big nobbly tyres I would get one a month, at least.
A colleague of mine who has cycled for years and who never ever punctured was last month picked on by the fairy in a most unfair and bullying manner. The fairy would wait until he was working lates and then get him on the way home. Somehow the fairy also invoked wind, rain and a noxious mix of road dirt. 4 times did the fairy attack in as many journeys. The fairy broke him. He sold the bike, helmet, lycra, shoes... everything!

What tyres do you use for touring, Mick?

Average about every 3000 miles for me I reckon. Something I'm happy with.

As others have said, use decent tyres with some puncture resistance and the right (higher) pressure. Over the years I seem to have suffered far fewer punctures since buying a track pump with a good gauge. I ride on road, with a bit of sustrans gravel and canal paths. Fortunately I can generally avoid riding on glass strewn cycle paths.

Reading some of the posts on this thread makes me feel as if I live in a different universe. In the winter months, once the lanes become permanently mucky, I average just over two punctures every week! And this average remains constant through years of experimentation with different tyres, sizes, pressures etc. The only rational explanation I can think of is the same as the thesis I propounded in another thread, about different riders experiencing widely different rates of chain wear. I suspect it's all down to the nature of the small mineral fragments in the local soils which wash out as mud on to the road surface. The size, shape and hardness of these fragments is a consequence of the underlying local geology. I happen to live in an area infested by quartz fragments of just the right size and shape to penetrate a tyre casing.

I think we need your location Chris, for avoidance purposes.

I have 23cs. They wouldn't be likely to see a pavement, gutter or a farm track. It's not what they're for. The Puncture Fairies who live in those habitats have long fangs and claws and you need thicker rubber to defend against them.

Quite. I've had one in two years, if we ignore the delaminating valve I found recently. When I had the one I just deployed my spare inner tube. One of my companions said 'I've never seen a puncture fixed so quick.' But of course I wasn't fixing it.

Every 700 miles on AVERAGE.

It used to be every 70 miles when I started due to tyres without a puncture belt and rim tapes with sharp corners, both of which were disposed of.

If I hadnt kept a record of the punctures I would have said about every 3,000 miles because

a) Most of my punctures are fixed at home as I inspect the tyres and remove thorns in the comfort of my workshop rather than out on the road.

b) It is common to get the punctures occurring in clusters, leaving you with thousands of puncture free miles in between.

When I saw this thread I thought "I had a roadside puncture not long ago after a run of having none" it was over 800 miles ago. The last one that I can think of was over a year ago but I am obviously forgetting all the ones fixed the day after.

Now it is September, the Fairy will be calling on all the local farmers to sprinkle my lanes with Blackthorn as a sacrifice to her.

I've cycled through mid Devon many times, and "Tiverton-ish" a dozen times or more. I rode to Exeter and back the other day - and along the canal bank.

Still no punctures!
