世帯数 (setaisuu) refers to the number of household units as social/economic entities, while 戸数 (kosuu) can refer to the number of physical housing units or doors. In many contexts they overlap, but for official population statistics, 世帯数 is preferred. For real estate, 戸数 is more common.
When counting households, use the counter 世帯 (setai) or 戸 (ko). For example, 1世帯 (いっせたい), 2世帯 (にせたい), or 1戸 (いっこ), 2戸 (にこ). Note that 戸 uses the counter 戸 (こ) with irregular readings for 1, 6, 8, 10.
