If you want to top up your income without taking on a strenuous second job, your first port of call should be your very own skillset. If you have a natural talent that could help others, you have an instant “in” to easy money. Whether you’re a gifted guitarist, mathematical genius or speak a second language, almost any talent can be turned into cash. Offering one-to-one coaching is a flexible way to make a solid hourly rate, and enables you to take on as much or as little work as you wish. Find local clients by placing adverts in the library, schools and community bulletin boards and share your talent in exchange for a fee.
Ebooks are one of my favorite sources of passive income. Now, you can do this the simple way and just publish it on Amazon's KDP. Or, you can go all out and build yourself a book funnel. Book funnels are powerful, but they won't be fully passive. For example, if you do a free-plus-shipping offer for your ebook (converting it into a physical book), you'll need to create some one-time offers (i.e. extra training) and up-sells (i.e. an audiobook). But, a book funnel can be very powerful.
There is a specific tax definition of passive income, known as “passive activity” to the Internal Revenue Service. Passive income is any income you make without actively working or are materially involved. The IRS defines it as any rental activity or any business in which the taxpayer does not “materially participate.” Nonpassive activities, or active activities, are businesses in which the taxpayer works on a regular, continuous, and substantial basis.

India is ranked 100th out of 190 countries in the World Bank's 2018 ease of doing business index, up 30 points from the last year's 130. This is first time in history where India got into the top 100 rank. In terms of dealing with construction permits and enforcing contracts, it is ranked among the 10 worst in the world, while it has a relatively favourable ranking when it comes to protecting minority investors or getting credit.[18] The strong efforts taken by the Department of Industrial Policy and Promotion (DIPP) to boost ease of doing business rankings at the state level is said to impact the overall rankings of India.[147]

Distribution of family income - Gini index measures the degree of inequality in the distribution of family income in a country. The more nearly equal a country's income distribution, the lower its Gini index, e.g., a Scandinavian country with an index of 25. The more unequal a country's income distribution, the higher its Gini index, e.g., a Sub-Saharan country with an index of 50. If income were distributed with perfect equality the index would be zero; if income were distributed with perfect inequality, the index would be 100.
The five-year plans, especially in the pre-liberalisation era, attempted to reduce regional disparities by encouraging industrial development in the interior regions and distributing industries across states. The results have been discouraging as these measures increased inefficiency and hampered effective industrial growth.[397] The more advanced states have been better placed to benefit from liberalisation, with well-developed infrastructure and an educated and skilled workforce, which attract the manufacturing and service sectors. Governments of less-advanced states have tried to reduce disparities by offering tax holidays and cheap land, and focused on sectors like tourism which can develop faster than other sectors.[398][399] India's income Gini coefficient is 33.9, according to the United Nations Development Program (UNDP), indicating overall income distribution to be more uniform than East Asia, Latin America and Africa.[10]
Stocks (shares) paying dividends are typically a reliable source of income but they have higher risk of capital losses than cash and bonds. So, it’s wise not to chase yield indiscriminately.  The 10 highest yielding stocks on the ASX 200 (the 200 largest companies in Australia) are shown in the table below.  But their share price performance on average over the last year has been underwhelming, as shown in the far right column:
