To accelerate growth in China, India, Brazil, and other large emerging markets, it isn’t enough, as many multinationals do, to develop a country-level strategy. Opportunities in these market are also rapidly moving beyond the largest cities, often the focus of many of these companies. For sure, the top cities are important: by 2030, Mumbai’s economy, for example, is expected to be larger than Malaysia’s is today. Even so, Mumbai would in that year represent only 5 percent of India’s economy and the country’s 14 largest cities, 24 percent. China has roughly 150 cities with at least one million inhabitants. Their population and income characteristics are so different and changing so rapidly that our forecasts for their consumption of a given product category, over the next five to ten years, can range from a drop in sales to growth five times the national average.
