An interface for several Australian socio-economic indexes.

The Australian Bureau of Statistics (ABS) publishes a variety of indexes for the Australian
economic environment. These include the Consumer Price Index (CPI) used for calculating inflation
and a variety of indexes designed to measure socio-economic advantage. `ausdex` makes these data
available in a convenient Python package with a simple programatic and command line interfaces. 

## Installation

You can install `ausdex` from the Python Package Index (PyPI):

```
pip install ausdex
```

## Command Line Usage

Adjust single values using the command line interface:
```
ausdex inflation VALUE ORIGINAL_DATE
```
This adjust the value from the original date to the equivalent in today's dollars.

For example, to adjust $26 from July 21, 1991 to today run:
```
$ ausdex inflation 26 "July 21 1991" 
$ 52.35
```

To choose a different date for evaluation use the `--evaluation-date` option. e.g.
```
$ ausdex inflation 26 "July 21 1991"  --evaluation-date "Sep 1999"
$ 30.27
```

By default, `ausdex` uses the CPI for Australia in general but you can calculate the inflation for specific capital cities with the `--location` argument:
```
$ ausdex inflation 26 "July 21 1991"  --evaluation-date "Sep 1999" --location sydney
$ 30.59
```

Location options are: 'Australia', 'Sydney', 'Melbourne', 'Brisbane', 'Adelaide', 'Perth', 'Hobart', 'Darwin', and 'Canberra'.


## Module Usage

```
>>> import ausdex
>>> ausdex.calc_inflation(26, "July 21 1991")
52.35254237288135
>>> ausdex.calc_inflation(26, "July 21 1991", evaluation_date="Sep 1999")
30.27457627118644
>>> ausdex.calc_inflation(26, "July 21 1991", evaluation_date="Sep 1999", location="sydney")
30.59083191850594
```
The dates can be as strings or Python datetime objects.

The values, the dates and the evaluation dates can be vectors by using NumPy arrays or Pandas Series. e.g.
```
>>> df = pd.DataFrame(data=[ [26, "July 21 1991"],[25,"Oct 1989"]], columns=["value","date"] )
>>> df['adjusted'] = ausdex.calc_inflation(df.value, df.date)
>>> df
   value          date   adjusted
0     26  July 21 1991  52.352542
1     25      Oct 1989  54.797048
```

## Dataset and Validation

The Consumer Price Index dataset is taken from the [Australian Bureau of Statistics](https://www.abs.gov.au/statistics/economy/price-indexes-and-inflation/consumer-price-index-australia). It uses the nation-wide CPI value. The validation examples in the tests are taken from the [Australian Reserve Bank's inflation calculator](https://www.rba.gov.au/calculator/). This will automatically update each quarter as the new datasets are released.

The CPI data goes back to 1948. Using dates before this will result in a NaN.
