HMD.jl

Makes it easy to get data from Human Mortality Database (HMD) into Julia!

Installation

The package can be installed directly using the repo's URL

julia> using Pkg
julia> Pkg.add("https://github.com/patrickm663/HMD.jl")

If you want to tinker more with the internals, clone the repo, enter and activate!

git clone git@github.com:patrickm663/HMD.jl
cd HMD.jl/

julia
julia> using Pkg
julia> Pkg.activate(".")

Quick Example

Once in, load HMD

julia> using HMD
julia> df = read_HMD("AUS", "Mx", "1x1", "username", "password"; verbose=true);

julia> df
11100×5 DataFrame
   Row │ Year   Age    Female    Male      Total    
       │ Int64  Int64  Float64   Float64   Float64  
───────┼────────────────────────────────────────────
     1 │  1921      0  0.059987  0.076533  0.068444
     2 │  1921      1  0.012064  0.014339  0.013225
     3 │  1921      2  0.005779  0.006047  0.005916
     4 │  1921      3  0.002889  0.004197  0.003554
     5 │  1921      4  0.003254  0.003254  0.003254
...

It also supports long-form names:

julia> using HMD
julia> df = read_HMD("Australia", "Death Rates", "1x1", "username", "password"; verbose=true);
Checking inputs are valid...
Attempting initial connection...
Attempting to login...

Success!

julia> df

   Row │ Year   Age    Female    Male      Total    
       │ Int64  Int64  Float64   Float64   Float64  
───────┼────────────────────────────────────────────
     1 │  1921      0  0.059987  0.076533  0.068444
     2 │  1921      1  0.012064  0.014339  0.013225
     3 │  1921      2  0.005779  0.006047  0.005916
     4 │  1921      3  0.002889  0.004197  0.003554
     5 │  1921      4  0.003254  0.003254  0.003254
...

Data can then be transformed into matrix-form where ages are rows and years are columns using the transform() function:

julia> transform(df, :Total)
111×101 DataFrame
 Row │ Age    1921      1922      1923      1924      1925      1926      1927      1928      1929      1930      1931      1932      1933      1934      1935      1936      1937      1938      1939      1940      1941      1942      1 ⋯
     │ Int64  Float64?  Float64?  Float64?  Float64?  Float64?  Float64?  Float64?  Float64?  Float64?  Float64?  Float64?  Float64?  Float64?  Float64?  Float64?  Float64?  Float64?  Float64?  Float64?  Float64?  Float64?  Float64?  F ⋯

Additionally, locally saved .txt file from HMD can be loaded and processed - with the option to save as a CSV:

julia> using HMD
julia> df = read_HMD("test/data/Aus_Births.txt")
161×4 DataFrame
 Row │ Year   Female  Male    Total  
     │ Int64  Int64   Int64   Int64

Acknowledgements

The R package HMDHFDplus was a big help to figure out how to parse user-input correctly.

TODO

My TODO over the next while is:

• Figure out why docstrings aren't showing in the documentation
• Maybe refactor src/ to make it more modular
• Complete the README
• Add tests
• Better error handling
• Compile docs and run tests using Actions
• Check for valid country x table x group combos
• Add function to transform long-form DataFrames into $age \times year$ DataFrames
• Think about how to handle 'secret' credentials (testing and general use)
• Make it compatible with MortalityTables.jl
