[Inequality.jl](https://github.com/JosepER/Inequality.jl) has functions for the analysis of inequality and poverty indicators. It currently supports the estimation of the following (both weighted and unweighted):
- Gini Coefficient
- Atkinson Coefficient
- Lorenz Curve
- Generalized Entropy Index
- Theil Index
- Mean log deviation
- Watts Poverty Index
- Foster–Greer–Thorbecke Index
- Poverty Gap
- Headcount Ratio
It’s my first Julia package so coments, suggestions and contributions are more than welcome! 🙂

This looks like a very useful package to have for people working in those areas that’s well documented too!
I do feel that the name could have been chosen to be slightly more specific, such as `InequalityIndicators.jl` as it is more precise description of what the package provides and fits better with Julia’s package naming conventions.
I apologise that this is my only specific comment on the package (but perhaps this is a compliment to your documentation and concise code!).

Thanks very much for your feedback, Jacobus!
I’m planning to expand the package beyond the current indicators. Most likely including top-income adjustments and functions for processing income and wealth variables (e.g. equivalisations and CPI/PPP adjustments). Thus, I’ll probably keep the current general package name.

Hi,
I published [PovertyAndInequalityMeasures.jl](https://github.com/grahamstark/PovertyAndInequalityMeasures.jl) a while back, which covers much the same ground. Be interesting to see how they compare. Let a thousand flowers bloom and all that.

Thank you for the contribution.
The name means something very different to many Julia users,
“inequality” is of a field of mathematics and some computer science.
The orthographic root may be the same; the manner of consideration differs. Speaking for myself, I expected a package that provided tools for investigating or establishing inequations (a = b + c, an equation … replace `=` with another comparative relationship and there are many uses for the sort of expressions that result, see [Inequality of arithmetic and geometric means - Wikipedia](https://en.wikipedia.org/wiki/Inequality_of_arithmetic_and_geometric_means)). A name like that suggested above `InequalityIndictors` or `EconomicInequalities` or what you find more explanatory would help.

Thanks for your feedback, Jeffrey.
I now see why the package name might lead to confusion. I’ll seriously think about changing it.

Hi Graham.
I checked for other packages in the area before writing mine, but I completely missed yours. It’s great to see there’s other people working on inequalities/poverty using Julia!

Yes, when I saw the package name, I expected a package for solving mathematical inequalities.

Yes, it’s good to see someone interested in the same stuff. It would be great to see a suite of survey-data related things in Julia, rather like R has. My wishlist includes:
- survey data weighting: I’ve got an [implementation](https://github.com/grahamstark/SurveyDataWeighting.jl) that does the job but could do with a lot of development and testing;
- data matching. Like the [R Statmatch package](https://cran.r-project.org/web/packages/StatMatch/index.html);
- multidimensional poverty and inequality;
- a nice tabulator, kind of like SPSS has.
You also mention equivalence scales in your bio. I have [a bunch of these](https://github.com/grahamstark/ScottishTaxBenefitModel.jl/blob/master/src/EquivalenceScales.jl) in a [sub-package of my tax-benefit model](https://github.com/grahamstark/ScottishTaxBenefitModel.jl). It’s inelegant code, but might be a start.
I’ll have a good look at your package. Looks more elegant than mine …
Graham
