SQLite vs Core Data: saving large amounts of data

I'm making a statistical analysis app which needs to store large amounts of data locally. To give you an idea of what I'm talking about, I've made this illustration (not exactly the right information, but very similar):

The app will keep track of several thousand destinations, with the destinations population, temperature, number of cars etc. These numbers will be represented in a graph so that you can look at the numbers "development" over time. This will go over a long period of time, in other words: thousand of dates for each data-type for each thousands of cities.

To achieve this I need to save large amounts of data, and it is preferred to be done locally (is that crazy?). I'm stuck between digging deep into the foundation of Core data, or using my already decent skills in SQLite.

If you suggest I should use SQLite, could you refer to how you would implement this into your app (some code perhaps?).

If you suggest I should use core data (mainly for performance), please show me how you would implement this type of data model with entities, attributes, relationships etc. I can imagine using dictionaries saved in the core data would be a good solution?

Thank you in advance.
