Estimating from the global population, which is approximately 7.9 billion people as of mid-2024, and considering the niche and specialized nature of the "anti-psychiatric model of micro-utopias," we can attempt to provide a rough estimate:
Let's use the assumption that the adoption rate could be less than 0.1% of the global population.
0.1% of 7.9 billion = 0.001 * 7,900,000,000 = 7,900,000 people.
Therefore, based on this estimate, less than 0.1% of the global population, which equates to roughly 7.9 million people, might be involved in or supportive of initiatives related to the "anti-psychiatric model of micro-utopias."
Again, this is a speculative estimate based on the assumption that these movements are niche and not widely adopted globally. Actual numbers could vary and would require more specific data or studies to provide a more accurate figure.
