Nearly every misleading claim about Accra comes from one of a small number of mistakes, and they are all avoidable. This is the guide behind the data page, and it applies just as well to a figure you read in a newspaper.
Mistake one: quoting Ghana and saying Accra
This is by far the most common, and it is why every chart on this site’s data page carries a badge saying what it covers.
Of every series on that page, almost all of it is national. Ghana does not publish GDP, inflation, unemployment or school enrolment by region as an annual series. So when you see “Accra’s inflation rate” or “Accra’s GDP”, it is almost always a national figure that lost its label somewhere.
There are exactly three kinds of figure on that page:
| Scope | What it is |
|---|---|
| Accra | Greater Accra itself. 6 census counts, and that is very nearly the whole of it |
| Ghana | National. Sixty-odd years of it, labelled Ghana and never Accra |
| Derived | Arithmetic on two sourced figures, such as Accra’s density or its share of the national population |
If a number about Accra is not one of those, ask where it came from.
Mistake two: treating an estimate as a count
These are three different things and they get quoted identically:
- A count. A census is enumerators knocking on doors. Greater Accra’s 5,455,692 in 2021 is a count.
- An estimate. Ghana’s population in a year between censuses is modelled forward from the last count using assumed births, deaths and migration. Most of the population series is estimates.
- A model. Ghana’s unemployment rate of 2.98% is largely an ILO modelled estimate, harmonised so countries can be compared. It is not the answer to “how many people in Accra need work”.
The census runs roughly once a decade, so any current population figure for Accra is an extrapolation from 2021. That is fine. Pretending otherwise is not.
Mistake three: a multiple across a currency change
Ghana’s exchange-rate series looks like it moved by a factor in the hundreds of thousands. It did not. Ghana changed currency in 1965 and went through a redenomination in July 2007, when 10,000 old cedis became one new Ghana cedi. The series is expressed in today’s cedis throughout, so its early years are fractions of a pesewa.
Any long-run multiple across that is arithmetic on two different units.
Mistake four: nominal dollars read as real growth
Ghana’s GDP went from $1.2 billion to $114.2 billion — a multiple of about 93.8. Ghanaians are not 93.8 times better off.
Both figures are in current US dollars: each year is priced in that year’s money at that year’s exchange rate. The multiple therefore contains sixty-five years of global inflation, the cedi’s whole depreciation history, and population growth, before you get anywhere near a change in living standards.
The rule: if a long-run money comparison is not in constant prices, it is not a comparison. Growth rates and per-person figures are safer, and even those need care.
Ghana has also rebased its national accounts more than once — the 2010 rebasing raised measured GDP by around 60% overnight and moved Ghana into the lower-middle-income bracket. Nothing changed in the country that week. The measurement changed.
Mistake five: reading the shape of a sparse series
The clearest example on the whole dashboard is adult literacy, which has 5 observations across two decades:
| Year | Adult literacy |
|---|---|
| 2000 | 57.9% |
| 2010 | 71.5% |
| 2015 | 60.2% |
| 2017 | 64.5% |
| 2021 | 76.5% |
It goes up, drops eleven points, then goes up again. Ghanaian adults did not unlearn reading. Those five figures come from different surveys with different questions, age ranges and definitions of what counts as literate.
A sparse series stitched from mixed sources supports a statement about its endpoints and nothing about its shape. This site’s charts draw the observations as dots rather than a smooth line for exactly this reason — where the data is sparse, the gap is visible.
Mistake six: a definition that means something else
Three that catch people constantly:
- Unemployment requires having done no paid work at all and actively looking. In an economy where 66% of workers in a typical Greater Accra district are informal, a low unemployment rate is compatible with widespread underemployment.
- Access to electricity means a connection exists, not that power arrives. That gap has a Ghanaian name: dumsor.
- Mobile subscriptions per 100 people exceeds 100 because people carry several SIMs, not because everyone has a phone.

How to check any of it yourself
World Bank series. Every national figure on the data page names its
indicator code, like NY.GDP.MKTP.CD. Put the code into
data.worldbank.org and you get the
same series, the same definition and the same revision history. If this site
disagrees with the World Bank, the World Bank is right and this site has a bug.
Census figures. The GSS publishes the 2021 census reports and a StatsBank database. Greater Accra’s regional total is 5,455,692, and this site refuses to build unless its 29 district figures sum to exactly that — which is what catches a double-counted sub-metro.
Everything else on this site. Every cedi figure in every guide carries the source it came from, the date it was last checked and a date it expires. When one expires, the build fails until somebody re-checks it.

What good practice looks like
If you are writing about Accra:
- Say Accra or Ghana. Never let the reader guess.
- Give the year. A figure without a year is not a figure.
- Name the source, and prefer the primary one over the news article about it.
- Publish the range if the source gives a range. Accra’s share of national GDP is 34 to 39% across 2015–2020, not “a third”, and certainly not “a third last year”.
- Say when there is no data. “Ghana does not publish this” is a complete and respectable answer, and it is the right one more often than people admit.
If you find an error here
Numbers on this site are wrong sometimes. Checking its own startup-cost figures against real prices recently moved the range for a layer unit sharply upward, because the original had never accounted for what a pullet eats before it starts laying — about sixty bags of feed for five hundred birds, which turns out to dominate the whole budget.
Corrections are the point of publishing the reasoning, and every figure here names its source so you can go and disagree with it.
