Methodology
Each indexed city is associated with a reference basket of common living costs (for example rent, groceries samples, transport tickets, utilities, restaurant meals, and net salary where available). From those items, the platform derives relative indices such as CPI, rent, groceries, restaurants, and local purchasing power, using New York City = 100 as the familiar baseline convention for relative comparison.
