Challenge 7
We’re going to look at the total income of households in the USA based on the census. Here we would like to split and compare the households.
I have split the data set into different dataframes based on the identifier given to the respondents, e.g. white, Black, Asian or Pacific Islander, etc. Below we have the table of income of all races from 1967 to 2019. The table is split into percents of respondents falling under a bracket, and total percent equals 100.
Here, I have a graph of all respondents regardless of race and their income. Based on percent of respondents, we can see the progression. Since inflation does occur over the years, this graph must be adjusted for inflation before any real statistical inferences can be drawn from it.
The above plots are comparing the plots generated to view side-by-side comparisons of white and Black respondents whose income falls below what is currently considered the poverty line. As inflation does affect the interpretation of these numbers, we must consider that in 1967, $15,000 is worth $152,957.43 in today’s buying power. There was an average of inflation of 3.75% each year since 1960, leading to current prices and a total increase of 919.72%.
