Final answer:
The Huli people-related question lacks context, and specific demographic information for that group in the 1950s might be hard to find. Instead, examples of population growth have been given, ranging from ancient China's stability and growth to the Indigenous populations of the Western Hemisphere at European contact.
Step-by-step explanation:
The question 'Where do they live and how large was their population in the 1950s. (Huli)' seems to be inquiring about the Huli people of Papua New Guinea. This question requires clarification as the context is vague; however, if it refers to the population of a specific group in the 1950s, data might not be readily available for that precise period, especially for indigenous groups such as the Huli, whose census figures were not comprehensively recorded during the era. When discussing population growth and demographics under historical contexts, an understanding can be gleaned from examples like the Indigenous populations of the Western Hemisphere and China, where population numbers remained relatively stable or grew significantly over centuries.
For instance, in the mid-Han dynasty around the year 2 AD, China had approximately 60 million inhabitants, and by 980 AD the Song dynasty presided over 100 million people. Similarly, at the time of European contact, the Indigenous population of the Western Hemisphere was estimated to be 43-65 million people. These examples illustrate the growth in population across different societies, which can be a measure of societal changes and a factor contributing to further development.
