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]
In 2012, even I wrote a 150-page eBook about severance package negotiations that still regularly sells about ~35 copies a month at $85 each (2nd edition for 2017) without any effort. In order to generate $2,975 a month or $35,700 a year in passive income as I do now, I would need to invest $892,500 in something that generates a 4% yield! To earn $10,000 a year in passive income would therefore need roughly $250,000 in capital.
You can select any of the above fields based on your skill sets to create second income source. There is no dearth of opportunities, only thing matter is to identify the right one, which suits you. There is no shortcut to success but you have to start journey from some point. Recession can push your career 5 years back but with proper planning you can minimize its impact and remember Bad Times also don’t last forever.
Investing in coins and collectibles: Buffalo nickels and Spiderman comic books are good examples of coins and collectibles that can rise in value, and thus offer opportunity for passive income investors. You'll need to get up to speed on the value of any coin or collectible under consideration, but once you do so, you're on the way to price appreciation on a commodity you'll be paying a lower price to buy, and will garner a higher price when you sell.
What's crazy is that my book income is more than my SF condo-rental income. Yet I didn't have to come up with $1.2 million of capital (the minimum cost to buy my condo today) to create my book. All I needed to create my book was energy, effort, and creativity. I truly believe that developing your own online product is one of the best ways to make money.
If you happen to own a home, apartment, or office space, you have a great source for generating passive income at your fingertips. Peer-to-peer property rental site Airbnb has made it extremely easy for real estate owners to make extra money by renting out their homes to guests for short durations. If you're uncomfortable with such a model, you can also use sites like NestAway to find tenants for your property without having to deal with brokers.

Civil aviation in India traces its beginnings to 18 February 1911, when Henri Pequet, a French aviator, carried 6,500 pieces of mail on a Humber biplane from Allahabad to Naini.[197] Later on 15 October 1932, J.R.D. Tata flew a consignment of mail from Karachi to Juhu Airport. His airline later became Air India and was the first Asian airline to cross the Atlantic Ocean as well as first Asian airline to fly jets.[198]

Venture debt ($12,240 a year): The first venture-debt fund has returned almost all my initial capital, so I decided to invest $200,000 in the second fund. I took a risk investing $150,000 in my friend's first fund, so I'm hoping there's less risk in the second fund, given he has four more years of experience on top of his 12-plus years of experience running a venture-debt portfolio for another company.
That is a nice list of passive income sources. Actually, the most up-to-date list of dividend growth stocks is the list of dividend champions, maintained by Dave Fish. The list of dividend aristocrats is incomplete at best. For example, the dividend champions list has over 100 companies that have managed to increase dividends each year for at least 25 years in a row. The list of dividend aristocrats has no more than 50 – 60.

Thirst for income is likely to continue with interest rates expected to stay low, keeping government bond yields low for longer and their valuations unattractive.  Looking past bonds, the prices of high-dividend shares are historically high, which limits the likelihood that their dividends will rise markedly from here.  Striving too high for an income target tends to push your portfolio further out on the risk spectrum.
