The 1872 census revealed that 91.3% of the population of the region constituting present-day India resided in villages.[111] This was a decline from the earlier Mughal era, when 85% of the population resided in villages and 15% in urban centers under Akbar's reign in 1600.[112] Urbanisation generally remained sluggish in British India until the 1920s, due to the lack of industrialisation and absence of adequate transportation. Subsequently, the policy of discriminating protection (where certain important industries were given financial protection by the state), coupled with the Second World War, saw the development and dispersal of industries, encouraging rural–urban migration, and in particular the large port cities of Bombay, Calcutta and Madras grew rapidly. Despite this, only one-sixth of India's population lived in cities by 1951.[113]
“The biggest surprise is real estate being second to last on my Passive Income Ranking List because I’ve written that real estate is my favorite investment class to build wealth. Real estate doesn’t stack up well against the other passive income sources due to the lack of liquidity and constant maintenance of tenants and property. The returns can be huge due to rising rental income AND principal over time, much like dividend investing. If you are a “proactive passive income earner” like myself, then real estate is great.”
IDA has invested more than $2 billion since 1991 to address the country’s infrastructure gap, partly through the Road Sector Development Program (RSDP). IDA helped build capacity and establish a dedicated road fund for financing maintenance. Working in partnership with other donors, including the European Commission, Germany, Japan, Nordic countries and the United Kingdom, IDA helped increase both the size and quality of Ethiopia’s road network from under 20,000 km in 1991 to over 100,000 km in 2015. Under the CPF, the World Bank continues supporting improvements in transport infrastructure and road connectivity to reduce travel times and improve connectivity between markets and secondary cities.
In focusing on your wealth management goals, investment income is obviously critical but you might fund your goals from wider sources of income.  A typical long-term portfolio might produce about half its return as income and the other half as capital growth, though in times of duress the capital growth component wanes.  In this low-interest rate climate, some sources of income have become quite expensive and may prove disappointing against your spending needs.  But by tax efficiently and sustainably drawing income from wider sources, you might meet your goals while more prudently balancing risk against reward.
