   1 = "Household Composition (EIA)" represents an equivalent category with previous household transportation studies conducted by the Energy Information Administration (EIA).
   2 = "Household Composition (NHTS)" represents an equivalent category in the National Household Travel Survey (NHTS) conducted by the U.S. Department of Transportation.
   # underlined = Estimate, when rounded, displays as a zero value. 
   # in red, italic format = Data withheld either because the relative standard error was greater than 50 percent or fewer than 10 reporting units were sampled.
   Notes: ▪ "Gallons" and "Miles Per Gallon" are displayed in Gallon of Gasoline Equivalent (GGE) units due to the non-gasoline and diesel vehicles in the augmented NHTS data.  ▪ Data in this table are for households with passenger vehicles operated for residential transportation.  ▪ See glossary for definitions used in this table.  ▪ "Income Relative to Poverty Line" category was calculated by evaluating the categorical average of household with Poverty Thresholds for 2001 by Size of Family and Number of Related Children Under 18 Years (http://www.census.gov/hhes/poverty/threshld.html), as published by the U.S. Department of Commerce, U.S. Census Bureau.  ▪ Because of independent rounding, data may not sum to totals.  ▪ "Householder" is defined as the person identified as the household respondent by the NHTS.
