Ghana's 2021 census by region, district, age, sex and schooling, and mobile money use by place.
Scored across 3 tools
Each tool targets a clearly distinct output: a population count, a geography lookup, and a single mobile-money percentage. The descriptions explicitly fence off overlap (list_places for names before counting, count_people vs. mobile_money_reach by measure), so an agent can select correctly without guessing.
All three share a predictable namespace prefix (ghana.) and lowercase snake_case, which is good. However two use a verb_noun form (count_people, list_places) while mobile_money_reach is a noun phrase, a minor deviation from the pattern.
Three tools is a tight but defensible surface for a single-dataset census server, and each one has a clear job. It sits at the low end of the comfortable range, leaving little room for discovery of other available measures.
The surface covers population counts, geography lookup, and one indicator, but 'Ghana in Numbers' implies a broader statistical catalogue (education, employment, housing, etc.) with no tool to list available indicators or variables. An agent can answer a narrow set of questions but hits a dead end for most census topics.
Use this when someone wants to know how many people live in Ghana, one of its regions or one of its districts, optionally narrowed by age band, sex or schooling: for example to size a market, an audience or a programme. Counts come from Ghana's 2021 Population and Housing Census. Do not use it for other countries, for years other than 2021, for income or spending, or for forecasts.
Inputs: sex, region, age_band, district, +1 more. Returns: year, group, by_sex, people, +5 more
Use this when you need the exact name of a Ghana region or district before counting people there, or when someone asks which districts are in a region. Do not use it for towns, villages or addresses: the list holds regions and districts only.
Inputs: region. Returns: region, regions, districts
Use this when someone asks what share of people in Ghana, one of its regions or one of its districts use mobile money, or wants to compare mobile-money use between two regions. The figure is the share of people aged 6 and over who used a mobile phone for financial transactions in the 2021 census. Do not use it for a breakdown by age or sex (the census table has none), for transaction values, for a named provider's customer numbers, for years other than 2021, or for other countries.
Inputs: region, district, compare_region. Returns: year, place, source, definition, +4 more
