I walk my dog twice a day every day rain or shine. I've picked up his poop 100% of the time - as do most other members of my suburban community. Our parks and sidewalks are mostly dog poop free. Having said that, I've observed four cases where dog poop is more likely left behind. 1. Small dogs - owners of small dogs seem far more likely to leave dog poop behind. Perhaps because they think the poop is itself small? 2. Older owners (often owners of small dogs, but not always) - seem to care less. 3. Off leash dogs in parks - will often poop at the far edges of parks while their owners chat. Edges of parks and near bushes are minefields. 4. Rainy days - people just want to get home, clean off their dog and be done. So they seem more likely leave poop behind.
