I did include my deceased spouse for earlier years. No harm in including i guess if you meet the minimum income requirements@YULIA-2016 I asked the same question to tweeter "I am just wondering should family size counted by years? and should the person deceased in 2018 included in 2016 and 2017 family size and not in 2018 family size? what about decreasing family size, there is no any example. Thank you!" and I got this reply "Hi. Please include the deceased family members in family size for any year that they were alive." It is strange for me too, but...
