X poverty by Y year targets

per Gillian/Emma some new targets for interventions. using this issue as a discussion space for how to implement it.

Scotgov has four main aims to tackle poverty by 2030:

[x] fewer than 10% of childing living in families in relative poverty -> #336
[x] fewer than 5% of children living in families in absolute poverty -> #319
[x] fewer than 5% of children in families living in combined low income and material deprivation -> #331
[ ] fewer than 5% of children living in families in persistent poverty -> #335

absolute poverty households whose equivalised income is below 60% of inflation adjusted UK median income in 2010/11. this will be a constant number (subject to inflation?) relative poverty is below 60% of median disposable income (we already do this in poverty line) persistent poverty is 3/4 previous years in (relative?) poverty.

How do we estimate these targets in MINOS?

targets 1 and 2 seem straightforward. calculate equivalent income and count who falls below threshholds.
target 3 could be straightforwards as counting combined below poverty line and housing quality together? We may need a better housing quality composite to quantify material deprivaton.
target 4 likewise is doable. may run into missing data issues for 4 years of income. if we burn in MINOS from 2020-2023 would wehave the required data then? should be simple to increment number of years in poverty based on metrics for targets 1/2. If in poverty add one to a max of 4 or subtract 1 to a min of 0.

With these metrics we can simply track them over time. Look at 2030 and if the change in percentage is met. Will need to quantify uncertainty here. Using standard lineplots should be fine?

Can then apply any combination of policies to this we like.
