Analysis of information sources in references of the Wikipedia article "1978 California Proposition 13" in English language version.
In our recent Proposition 13 report (Figure 1), we showed the trend of all California local governments' property tax revenue in inflation-adjusted 2014–15 dollars, as shown below. For a series of financial data covering long periods of time, inflation-adjusted ("real") numbers generally are preferred to control for the changed buying power of money over time. This is because a dollar a few decades ago could buy the same amount of goods and services that it would take several dollars to buy today. The figure below shows that property taxes dropped sharply in 1978–79 after Proposition 13, and on an inflation-adjusted basis have grown in the decades since. In 2014–15 dollars, property taxes rose to $40.8 billion before Proposition 13, fell to $18.0 billion after the measure's passage, and reached $55.5 billion in 2014–15.
For each state, we calculate the total amount paid by the residents in taxes, then divide those taxes by the state's total income to compute a "tax burden." ... The goal is to focus not on the tax collectors but on the taxpayers. That is, we answer the question: What percentage of their income are the residents of this state paying in state and local taxes? [Note that these rankings count not only tax paid to their home state, but also taxes paid to other states as part of a resident's tax burden.]
