Just clocks, or every time piece? Working clocks, or including those that don't work?
Most cell phones and computers have built in clocks. Wrist watches come in a wide variety. Cars have clock radios, and sometimes separate clocks. Microwave ovens and stoves are other places one might find clocks, aside from the bedroom alarm clock, and the office clock or time punch clock, business phone and security systems. Many people in developed countries will have four or five timepieces per person, and I'd venture a guess that even most of those in the undeveloped world now carry a time piece.
There are 6.7 billion people on the earth. My estimate is that there are 8 to 10 billion "clocks."
Pendulums are often used in clocks to power the gears that move the hands. However, most clocks built today often have pendulums only for show, as those types of clocks are usually inaccurate and require a lot of winding.

They must. There is John Bouwman Clockmaker where they deal with antique and modern clocks and watches in buying, selling and restoring. Watchmakers also repair and build clocks too if you are interested. While most clocks today are made in factories, Clockmakers still exist. Clockmakers today just most often repair as opposed to build and design clocks.
