BUILDING DOWN: U.S. homebuilders began work on a seasonally adjusted 604,000 homes last month, a 1.5 percent drop from June. That's half the 1.2 million homes per year that economists say must be built to sustain a healthy housing market.
SINGLE-FAMILY DOWN, APARTMENTS UP: Single-family homes, which represent 70 percent of home construction, fell 5 percent. Apartment building rose more than 6 percent. Building permits, a sign of future construction, declined 3.2 percent.
FEW HOMES BEING BUILT: The number of homes under construction is the fewest in 40 years. Just 413,000 homes are being built, after accounting for seasonal factors. A decade ago, roughly 1.6 million homes were built.
