Answer 2

select [Month], isnull([2016],0) [2016],isnull([2017],0) [2017] 
from 
(
    select * 
    from #Table1 
) src 
pivot 
(
    max([members]) 
    for [year] in ([2016], [2017]) 
) piv; 

OR

SELECT MONTH,MAX(CASE WHEN YEAR=2016 THEN MEMBERS ELSE '' END) [2016], 
MAX(CASE WHEN YEAR=2017 THEN MEMBERS ELSE '' END) [2017] FROM #Table1 
GROUP BY MONTH
