It's also worth pointing out that if you take the IBC as a sampling only, it's still a MUCH bigger sample than the Lancet study, and therefore more accurate.
But they are sampling different things.
The Lancet sampled the population. IBC samples the news. It's a very big sample of the news and therefore gives a very accurate picture of the news. But it does not sample the population. It does not give you a per capita death toll, it gives you a per news-article death toll.
More to the point, all experience indicates that such counts will under-estimate the total number of deaths. Surveying has been considered to be much more accurate than such counts. It was considered accurate when used in Congo, Sudan and many other places. But, suddenly, when used in Iraq it runs into so many walls. Why? During other wars, governments have been wrong about the number of dead. Why is the Iraqi government so able in this department?
[...] and there's also major issued with Lancet aspects for statistics that can be determined precisely - such as the number of death certificates issued.
How are death certificates counted? Who prints them? Who hands them out?
There are so many things that a bereaved family member cannot do without a death certificate for whoever died. Can they even bury their loved one in a cemetery without a death certificate? Can you just turn up with a dead body and say “Here, would you bury this for me?”
Then there’s insurance, inheritance, etc.
So the bereaved will make sure they get a death certificate. What happens after that? The counting isn’t automated, as far as I know. How many other jobs does an Iraqi doctor have to do. He HAS to give out the death certificate, because the family won’t leave him alone until he does. What does he do after that?
And, to top it all off, Les Roberts has given a measure which would blow Lancet-2 out of the water: the ratio of violent/non-violent deaths. IBC gives about 20,000 violent deaths a year. Iraq has a death rate of 5.26 per 1000 per year according to the CIA:
https://www.cia.gov/library/publications/the-world-factbook/fields/2066.html
That gives about 140,000 deaths a year.
Lancet-2 recorded 547 post-war deaths, about 300 of them violent. (Amongst 12,801 people in the survey). That's a very different ratio of violent/non-violent deaths.
So what is the actual ratio? I would have thought this was easy to get hold of. But reports from morgues/cemeteries don't give enough infomation.

THE number of dead Iraqi civilians counted at the Baghdad morgue hit 1100 in July, the highest toll in recent history, a British newspaper reported today, blaming the daily violence.
[…] The death toll was up from about 800 in July last year and 700 during the same month in 2003, according to the left-wing daily.
By comparison, equivalent figures for July 1997, 1998 and 1999 - during the leadership of former Iraqi president Saddam Hussein - were all below 200, The Independent said.
Many of today’s corpses were badly mutilated, meaning that between 10 and 20 per cent of them were never identified, the newspaper said.
Since January, the medical authorities have buried 500 nameless bodies.
From 200 to 1100.
The Lancet-2 report only reckons the death rate went from about 5.5 to 13.3 per 1000.
So how many morgues closed? Why this big increase in the arrivals at one morgue? And that was from 2005 — much less violent than 2006 or 2007.
