Not as a percentage of the population. In 1967 the US population in 1967 was 200 million today it’s 350 million. Globally the growth was even faster.

Your farming productivity numbers are also very exaggerated. The actual percentage of the population was very high because of food spillage, and inconsistent productivity due to weather etc. They often needed ~90% of the adult population to be farmers or people starved, and famine was still common. Right before industrialization that number started to drop which is largely what caused industrialization. You got a positive feedback loop of increased productivity when a vastly larger percentage of the population could do something other than produce food.
