WASHINGTON (AP) — A rising stock market and climbing home prices boosted Americans' net worth to a new high in the first three months of the year. Total household debt, which includes mortgages, credit cards, auto loans and other borrowing, rose 2.2 percent, the slowest pace since the end of 2013. Household wealth, or net worth, reflects the value of homes, stocks and other assets minus mortgages, credit cards and other debts.
