According to sandag.org, 92127 zip code has a $74,570 median household income as of 2000 Census. Estimate for 2004 median household income is $80,001, 2010 is $85,092.
So to the original poster, you’re not making twice the median household for your area, you’re just making the median income and yes, you’re living beyond your means. $90,000 per annum is not that much in San Diego.
