The Luxury Institute annually surveys thousands of wealthy and ultrawealthy consumers about brands in many categories using its own, proprietary Luxury Brand Status Index to measure what it calls “the value and equity of leading luxury brands to wealthy Americans.” Using the LBSI, its watch survey polled “a nationally representative and statistically reliable sample” of more than 430 households with a minimum of $200,000 in gross annual income and minimum net worth of at least $750,000 (including home equity).
