Caveat: This answer features rampant personal speculation and anecdotal evidence. I personally the current dominance of flat bars in mainstream cycling is the result of two main events: The flood of cheap 10 speed knock-offs entered the market in the 70's and 80's. The explosion of MTB bikes in the 80's and 90's (which featured flat bars). Event 1: ...

Flat bars are easier to learn on than drop bars (unless the latter have interrupter brake levers). At this stage low speed manoeuvrability matters more than efficiency. Some people with small hands apparently have trouble braking firmly from the hoods and getting into the drops is tricky for a novice (I dismiss starting in the drops as I've never got on with ...

OPINION Drop bars should never have been popular. There was a surge in popularity for the "ten-speed" in the 70s and 80s, and part of that look was drop bars. This artificially made drops seem like a common thing and a good idea. As the MTB arrives in the 90s, flat bars re-exert themselves for the added width and leverage, returning drop bars to their ...

That looks like a 31.8mm clamp diameter, but the only way to be sure is to measure. Consider buying calipers. They're a useful tool, and tools are good to have. Otherwise, you can do this: take a strip of paper, fold it around the bar (at the thickest part, in the center), and mark the place on the paper where the two ends meet. Then put the paper flat, and ...

Calipers. A tape measure. Usually the stem clamp width is 25.4mm MTB and road. Rarely it could be 26mm. At the ends it goes down to 22mm. You might have an oversize bar in which case it is 31.8mm.

Is it a road dropbar or a MTB riser style bar? These two images should prove useful. If it is a mountain bike style riser or straight bar it's quite simple. If it's a road bar most people (zipp) measure center to center of the drops. Also if it is a Mountain bike were speaking of, most bars will be sold as 730mm or more wide and have pre-printed ...
