Last month Full Fact reported signs of improvement in the BBC complaints process.

Before our address to the Leveson Inquiry seminars, we had found that our complaints tended to be handled slowly and went unacknowledged, meaning we had no way of knowing the progress of any correction.

However when we submitted a complaint about the broadcaster's reporting of net migration last month, we were pleased to find that it was acknowledged immediately and responded to the next day.

But any hopes we had for a lasting improvement in the service seem to have faded once again.

Last week Full Fact found that the reporting of inequality statistics by the broadcaster failed to clarify key details when quoting figures from the OECD.

In the BBC's case, this was to state that the gap between the richest 10 percent and poorest 10 percent of British people stood at a ratio of 12:1.

In fact, as the OECD confirmed to Full Fact, this figure only referred to working-age persons. The figure for all 'British people' was in fact 10:1 - a figure which Sky News and the Financial Times both chose to report.

Following the investigation last Tuesday, Full Fact decided to submit a complaint to the BBC requesting a clarification to the published figures. This recieved no acknowledgement and no changes were made to the original article. Hence the statistic continues to be used incorrectly on the BBC site.

Now more than a week later, Full Fact has resubmitted the complaint and in the hope that this time it will be properly considered.

The text of our resubmission is below:

----------

Hello,

Further to my comments to you a week ago, I would like to mention again my complaint against your article: "Wage inequality 'getting worse' in leading economies", dated 5 December 2011.

The reason for my complaint regarded the following paragraph of the article in which I believe you cite a factual inaccuracy: "The average annual income for the richest 10% of British people in 2008 was £55,000 - which is 12 times higher than the average for the bottom 10%."

These statistics are from the OECD - however I believe you may have been imprecise in stating them. The 12:1 ratio of richest decile to poorest decile in terms of income uses a sample only of "working age" people in the UK. However, you said "British People" rather than specifying the section of the population concerned.

As the OECD data also confirmed, the correct ratio with a sample of all British people is 10:1, not 12:1 as you stated. The following sources will be of use in confirming this:

http://www.oecd.org/document/40/0,3746,en_21571361_44315115_49166760_1_1...

http://www.oecd.org/dataoecd/40/22/49170234.pdf

Since you state the £55,000 figure, which concerns the 12:1 ratio, I assume the error was in failing to specify the sample concerned rather than mis-typing the ratio. I therefore hope that you will add the clarification that your figure refers only to working-age British people rather than all British people.

If possible, an acknowledgement that you have received this message would be appreciated.
