Methods for data sample consistency

I would like to ask you for your opinion:

I have one data sample, letīs say with 600 units used for calculating some statistics (for example mean, std. deviation, q-o-q changes etc.) between the years 2006 and 2016. But from 2017 I would like to extend this data sample to letīs say 700 observations (with former units preserved).
Now I deal with a certain inconsistency because now I wonīt be able to compare mean, std. deviation, q-o-q changes and so on. Those two time series 2006-2016 and 2017 onwards are now not comparable with data sample changed.
Are there any statistical methods or some transformation bridge of how to deal with this inconsistency to make possible to have one coherent time series?

Thank you very much for any comments.

I have ten units across a geographical region where people attend for various functions. At each unit the attendees are looked after by four different sets of people. The attendees have rated each set of people on a scale of 1-4 depending on the quality of their care. I have a chart with the ten units across the Y-axis and four horizontal line charts with the X-axis being the score each set of people receive in each unit. I can see from viewing my charts and data that there is a correlation with how the attendees perceive the care they receive as each line progresses uniformly from unit to unit, ie. if the score for a particular set of carers in unit A was low, then the score for all sets of carers would be low, and vice versa. I initially tried a Spearman's rank correlation coefficient and Pearson product-moment correlation coefficient, but I'm not sure that these can be used for this data set. Can anybody advise on how I can statistically confirm a significant relationship as I have described from unit to unit. Many thanks.

Does anyone know of this information, where I can locate the information and how recent this information is?
