wbpy
A Python interface to the World Bank Indicators and Climate APIs.
The Indicators API lets you access a large number of world development indicators - country data on education, environment, gender, health, population, poverty, technology, and more.
The Climate API lets you access modelled and historical data for temperature and precipitation.
Why use wbpy?
- Dataset models let you access processed data and associated metadata in different formats.
- If you don’t want processed data objects, you can still access the raw JSON response.
- Single method calls to do the equivalent of multiple API requests, eg. wbpy handles the specific date pairs which would otherwise be required for the Climate API.
- Works with both ISO 1366 alpha-2 and alpha-3 country codes (the web APIs mostly just support alpha-3).
Elsewhere, there is also wbdata, a wrapper for the Indicators API which supports Pandas structures and has some command-line functionality.
Installation
pip install wbpy, or download the source code and python setup.py install.
Contributors
- @bcipolli upgraded wbpy to support Python 3 and v2 of the world bank API.
Development and maintenance
This project was unmaintained for a couple of years, although was updated in July 2020 to support Python 3 and to use the v2 endpoint of the API, as v1 has not been supported for a while (thanks @bcipolli). Although I’m not actively adding new features or looking for issues, I’m happy to accept contributions, and to provide commit access if anybody wants to work on the project.
Indicators API
Basic use
Here’s a small case where we already know what API codes to use:
import wbpy
from pprint import pprint
api = wbpy.IndicatorAPI()
iso_country_codes = ["GB", "FR", "JP"]
total_population = "SP.POP.TOTL"
dataset = api.get_dataset(total_population, iso_country_codes, date="2010:2012")
dataset
http://api.worldbank.org/v2/countries/GBR;FRA;JPN/indicators/SP.POP.TOTL?date=2010%3A2012&format=json&per_page=10000
<wbpy.indicators.IndicatorDataset('SP.POP.TOTL', 'Population, total') with id: 140421139962456>
The IndicatorDataset instance contains the direct API response and various metadata. Use dataset.as_dict() to return a tidy dictionary of the data:
dataset.as_dict()
{'FR': {'2012': 65659809.0, '2011': 65342780.0, '2010': 65027507.0},
'GB': {'2012': 63700215.0, '2011': 63258810.0, '2010': 62766365.0},
'JP': {'2012': 127629000.0, '2011': 127833000.0, '2010': 128070000.0}}
Some examples of the metadata available:
dataset.api_url
'http://api.worldbank.org/v2/countries/GBR;FRA;JPN/indicators/SP.POP.TOTL?date=2010%3A2012&format=json&per_page=10000'
dataset.indicator_name
'Population, total'
dataset.indicator_topics
http://api.worldbank.org/v2/indicator/SP.POP.TOTL?format=json&per_page=10000
[{'id': '19', 'value': 'Climate Change'}, {'id': '8', 'value': 'Health '}]
dataset.countries
{'FR': 'France', 'GB': 'United Kingdom', 'JP': 'Japan'}
If you want to create your own data structures, you can process the raw API response:
dataset.api_response

'pages': 1,
'per_page': 10000,
'total': 9,

Searching for indicators
We don’t always know what indicators we want to use, so we can search:
population_indicators = api.get_indicators(search="population")
len(population_indicators)
http://api.worldbank.org/v2/indicator?format=json&per_page=10000
1591
Ah. That’s not a very manageable number. The API returns over 8000 indicator codes, and lots of them have “population” in the title. Luckily, most of those indicators don’t really have much data, so we can forget about them. You can browse the indicators with the best data coverage at http://data.worldbank.org/indicator, and you can pass common_only=True to throw away all indicators that aren’t included on that page:
population_indicators = api.get_indicators(search="population", common_only=True)
print("There are now only %d indicators to browse." % len(population_indicators))
http://api.worldbank.org/v2/indicator?format=json&per_page=10000 There are now only 246 indicators to browse!
We don’t want to print that many results in the documentation, so let’s filter some more. The API query string parameters are directly mapped to kwargs for each method. For the get_indicators method, this means we can filter by topic or source:
health_topic_id = 8
health_indicators = api.get_indicators(search="population", common_only=True, topic=health_topic_id)
print("We've narrowed it down to %d indicators." % len(health_indicators))
http://api.worldbank.org/v2/topic/8/indicator?format=json&per_page=10000 We've narrowed it down to 109 indicators.
Each indicator has a variety of metadata:
pprint(list(health_indicators.items())[2])
('SH.DYN.AIDS.FE.ZS',
{'name': "Women's share of population ages 15+ living with HIV (%)",
'source': {'id': '2', 'value': 'World Development Indicators'},
'sourceNote': 'Prevalence of HIV is the percentage of people who are '
'infected with HIV. Female rate is as a percentage of the '
'total population ages 15+ who are living with HIV.',
'sourceOrganization': 'UNAIDS estimates.',
'topics': [{'id': '8', 'value': 'Health '}, {'id': '17', 'value': 'Gender'}],
'unit': ''})
That data might be useful, but it’s not very friendly if you just want to grab some API codes. If that’s what you want, you can pass the results to the print_codes method:
api.print_codes(api.get_indicators(search="tuberculosis"))
http://api.worldbank.org/v2/indicator?format=json&per_page=10000 SH.TBS.CURE.ZS Tuberculosis treatment success rate (% of new cases) SH.TBS.DOTS Tuberculosis cases detected under DOTS (%) SH.TBS.DTEC.ZS Tuberculosis case detection rate (%, all forms) SH.TBS.INCD Incidence of tuberculosis (per 100,000 people) SH.TBS.INCD.HG Incidence of tuberculosis, high uncertainty bound (per 100,000 people) SH.TBS.INCD.LW Incidence of tuberculosis, low uncertainty bound (per 100,000 people) SH.TBS.MORT Tuberculosis death rate (per 100,000 people) SH.TBS.MORT.HG Deaths due to tuberculosis among HIV-negative people, high uncertainty bound (per 100,000 population) SH.TBS.MORT.LW Deaths due to tuberculosis among HIV-negative people, low uncertainty bound (per 100,000 population) SH.TBS.PREV Tuberculosis prevalence rate (per 1000,000 population, WHO) SH.TBS.PREV.HG Tuberculosis prevalence rate, high uncertainty bound (per 1000,000 population, WHO) SH.TBS.PREV.LW Tuberculosis prevalence rate, low uncertainty bound (per 1000,000 population, WHO)
There are get_ functions matching all API endpoints (countries, regions, sources, etc.), and the search parameter and print_codes method can be used on any of them. For example:
countries = api.get_countries(search="united")
api.print_codes(countries)
http://api.worldbank.org/v2/country?format=json&per_page=10000 AE United Arab Emirates GB United Kingdom US United States
More searching
If you’re not sure what to search for, just leave out the search parameter. By default, the get_ methods return all API results:
all_regions = api.get_regions()
all_sources = api.get_sources()
print("There are %d regions and %d sources." % (len(all_regions), len(all_sources)))
http://api.worldbank.org/v2/region?format=json&per_page=10000 http://api.worldbank.org/v2/source?format=json&per_page=10000 There are 48 regions and 61 sources.
The search parameter actually just calls a search_results method, which you can use directly:
pprint(api.search_results("debt", all_sources))
{'20': {'code': 'PSD',
'concepts': '3',
'dataavailability': 'Y',

'url': ''}}
By default, the search parameter only searches the title of an entity (eg. a country name, or source title). If you want to search all fields, set the search_full flag to True:
narrow_matches = api.get_topics(search="poverty")
wide_matches = api.get_topics(search="poverty", search_full=True)
print("%d topic(s) match(es) 'poverty' in the title field, and %d topics match 'poverty' in all fields." % (len(narrow_matches), len(wide_matches)))
http://api.worldbank.org/v2/topic?format=json&per_page=10000 http://api.worldbank.org/v2/topic?format=json&per_page=10000 1 topic(s) match(es) 'poverty' in the title field, and 8 topics match 'poverty' in all fields.
API options
All endpoint query string parameters are directly mapped to method kwargs. Different kwargs are available for each get_ method (documented in the method’s docstring).
- language:
EN,ES,FR,ARorZH. Non-English languages seem to have less info in the responses. - date: String formats -
2001,2001:2006,2003M01:2004M06,2005Q2:2005Q4. Replace the years with your own. Not all indicators have monthly or quarterly data. - mrv: Most recent value, ie.
mrv=3returns the three most recent values for an indicator. - gapfill:
YorN. If using an MRV value, fills missing values with the next available value (I think tracking back as far as the MRV value allows). Defaults toN. - frequency: Works with MRV, can specify quarterly (
Q), monthly (M) or yearly (Y). Not all indicators have monthly and quarterly data. - source: ID number to filter indicators by data source.
- topic: ID number to filter indicators by their assigned category. Cannot give both source and topic in the same request.
- incomelevel: List of 3-letter IDs to filter results by income level category.
- lendingtype: List of 3-letter IDs to filter results by lending type.
- region: List of 3-letter IDs to filter results by region.
If no date or MRV value is given, MRV defaults to 1, returning the most recent value.
Any given kwarg that is not in the above list will be directly added to the query string, eg. foo="bar" will add &foo=bar to the URL.
Country codes
wbpy supports ISO 1366 alpha-2 and alpha-3 country codes. The World Bank uses some non-ISO 2-letter and 3-letter codes for regions, which are also supported. You can access them via the NON_STANDARD_REGIONS attribute, which returns a dictionary of codes and region info. Again, to see the codes, pass the dictionary to the print_codes method:
api.print_codes(api.NON_STANDARD_REGIONS)
1A Arab World 1W World 4E East Asia & Pacific (developing only) 7E Europe & Central Asia (developing only) 8S South Asia A4 Sub-Saharan Africa excluding South Africa A5 Sub-Saharan Africa excluding South Africa and Nigeria A9 Africa C4 East Asia and the Pacific (IFC classification) C5 Europe and Central Asia (IFC classification) C6 Latin America and the Caribbean (IFC classification) C7 Middle East and North Africa (IFC classification) C8 South Asia (IFC classification) C9 Sub-Saharan Africa (IFC classification) EU European Union JG Channel Islands KV Kosovo M2 North Africa OE OECD members S1 Small states S2 Pacific island small states S3 Caribbean small states S4 Other small states XC Euro area XD High income XE Heavily indebted poor countries (HIPC) XJ Latin America & Caribbean (developing only) XL Least developed countries: UN classification XM Low income XN Lower middle income XO Low & middle income XP Middle income XQ Middle East & North Africa (developing only) XR High income: nonOECD XS High income: OECD XT Upper middle income XU North America XY Not classified Z4 East Asia & Pacific (all income levels) Z7 Europe & Central Asia (all income levels) ZF Sub-Saharan Africa (developing only) ZG Sub-Saharan Africa (all income levels) ZJ Latin America & Caribbean (all income levels) ZQ Middle East & North Africa (all income levels)
Climate API
There are two methods to the climate API - get_modelled, which returns a ModelledDataset instance, and get_instrumental, which returns an InstrumentalDataset instance. The World Bank API has multiple date pairs associated with each dataset, but a single wbpy call will make multiple API calls and return all the dates associated with the requested data type.
For full explanation of the data and associated models, see the Climate API documentation.
Like the Indicators API, locations can be ISO-1366 alpha-2 or alpha-3 country codes. They can also be IDs corresponding to regional river basins. A basin map can be found in the official Climate API documentation. The API includes a KML interface that returns basin definitions, but this is currently not supported by wbpy.
Instrumental data
The available arguments and their definitions are accessible via the ARG_DEFINITIONS attribute:
c_api = wbpy.ClimateAPI()
c_api.ARG_DEFINITIONS["instrumental_types"]
{'pr': 'Precipitation (rainfall and assumed water equivalent), in millimeters',
'tas': 'Temperature, in degrees Celsius'}
c_api.ARG_DEFINITIONS["instrumental_intervals"]
['year', 'month', 'decade']
iso_and_basin_codes = ["AU", 1, 302]
dataset = c_api.get_instrumental(data_type="tas", interval="decade", locations=iso_and_basin_codes)
dataset
<wbpy.climate.InstrumentalDataset({'tas': 'Temperature, in degrees Celsius'}, 'decade') with id: 140420664386392>
The InstrumentalDataset instance stores the API responses, various metadata and methods for accessing the data:
pprint(dataset.as_dict())

modelled_dataset
<wbpy.climate.ModelledDataset({'pr': 'Precipitation (rainfall and assumed water equivalent), in millimeters'}, {'annualavg': 'Annual average'}) with id: 140420644546936>
The as_dict() method for ModelledDataset takes a kwarg to specify the SRES used for future values. The API uses the A2 and B1 scenarios:

Cache
The default cache function uses system temporary files. You can specify your own. The function has to take a url, and return the corresponding web page as a string.
def func(url):
# Basic function that doesn't do any caching
from six.moves.urllib import request
return request.urlopen(url).read()
# Either pass it in on instantiation...
ind_api = wbpy.IndicatorAPI(fetch=func)
# ...or point api.fetch to it.
climate_api = wbpy.ClimateAPI()
climate_api.fetch = func
