To belong to the top 10%, an individual must earn about $65,500 per year (around $5,460 per month). To reach the top 1%, the threshold rises to about $250,300 annually ($21,860 per month). Unsurprisingly, most of the population earning at these levels is concentrated in Europe, North America, and Oceania.
