Wealth resources consist of home ownership, other real estate (second home, rented properties, etc.), net value of farm and business assets, stocks, checking and savings accounts, and other savings (money in savings bonds, life insurance policy cash values, etc.).  Wealth is measured in three forms: net worth, net worth minus home equity, and liquid assets.  Net worth consists of all the aspects mentioned above.  Net worth minus home equity is the same except it does not include home ownership in asset calculations.  Liquid assets are resources that are readily available such as cash, checking and savings accounts, stocks, and other sources of savings.  There are two types of assets: tangible and intangible.  Tangible assets most closely resemble liquid assets in that they include stocks, bonds, property, natural resources, and hard assets not in the form of real estate.
