Referential USD

The following table provides the inflator/deflator multiplier for calculating referential US dollars (rUSD, r$). It is based on the average value of the United States consumer price index for all urban consumers - US CPI-U Average (United States Bureau of Labor Statistics, 20101). The CPI-U is a useful index for comparing the cost of consumer goods and services (Williamson, 20113), and represents well the consumer patterns of about 80% of the U.S. population (excluding rural consumers, the military and institutional populations - Wikipedia, 20112).

The formula for calculating rUSD based on CPI-U is the following:

rUSD = nominal USD + (nominal USD * multiplier)
