Labour & Wages: The tracking of employment and pay across the UK

David Freeman and Nicola White join Miles to discuss how the Office for National Statistics (ONS) tracks employment and pay across the UK.

Transcript:

Hello and welcome again to Statistically Speaking, the Office for National Statistics podcast. In this episode, we enter the world of work and clock on for a shift with the ONS labour market team. We'll explore how they keep track of employment and pay across the UK and find out how the figures we hear so much about in the news should really be interpreted. At your service, are employees of the month, our head of labour market and household statistics David Freeman, and later on his colleague, senior statistician Nicola White.

David, let's start with the basics. And one common misconception you still hear around the official statistics on unemployment is that they're based on the number of people claiming out of work benefits. And so, the theory goes therefore, that they're subject to manipulation in some way. But to be absolutely clear, the figures don't come from any other government department. This is data that comes from the ONS talking directly to real people, in their tens of thousands. DAVID FREEMAN That's absolutely right, Miles. The bulk of the information that we publish as part of our labour market statistics come from something called the ‘Labour Force Survey’. As this is one of our big household surveys, every three months we sample 40,000 households across the UK. And we go and we interview the people in those households about their labour market status. So, are they working, are they not working. We also gather a lot of information about the people in those households, what age they are, whether they have got a disability, what ethnic group [they belong to], which gives a us rich picture of the UK labour market. MILES FLETCHER

And by the standards of any survey, any regular survey, that's a huge sample isn’t it. I know we don't go in for superlatives, but it's possibly the biggest household survey regularly undertaken of any kind? DAVID FREEMAN I think it is the biggest one in the UK, outside of the Census of course, and again, through the data that we use, we’ll learn about the labour market, but the data will also feed into things like population estimates. So quite a wide range of uses, but its core purpose is really trying to measure the UK labour market. MILES FLETCHER And it's that time spent with people to gather a whole raft of data from them, and at scale, that can give a localised picture, which is so important too. DAVID FREEMAN Absolutely, we get a lot of information from the Labour Force Survey, either by age groups, by country of birth, also by regional level, and we have an annual version of the Labour Force Survey where we put the data together across a longer time period, which means we can get data down to things like local authority levels as well which is important for local government. MILES FLETCHER

And how do we choose people to take part? DAVID FREEMAN

It’s a totally random process. So we have access to the postcode directory for the UK, which is effectively a list of all the households in the UK, and we take a random sample of those. However, we make sure within taking that sample that we're represented across the country. So within each local authority area, we've got enough people to be able to give us a robust estimate of what's happening there.

MILES FLETCHER

You stay in the survey a little while, don’t you?

DAVID FREEMAN

You do, that's right, and that's one of the strengths of the Labour Force Survey. If you're selected to take part, you are in there for what we call “five waves”. So if you're selected in January, we'll also come back and talk to you again in April, July, October and the following January. And that's important because not only do we find out what people are doing now, as you say we find out how people have changed, and whether they have moved into employment, out of employment, how have their circumstances changed. And that gives a deep insight into how people are flowing through the labour market and changing over time. MILES FLETCHER

So, big sample, lots of data coming in. When it comes to the analysis though, essentially, we group people under three big categories. Now the first of those is employment. It sounds self-evident, but what is the definition of an employed person? DAVID FREEMAN To be employed is to be someone who has done paid work in the reference week, so when we interview people we’ll say, what were you doing in the week before we're interviewing you? They are considered employed if they have done paid work for a minimum of one hour in that week. So the bar is, you could say it’s quite low, in terms of one hour of work a week. But we have looked, and not that many people work that little in a week – less than 3% of people work less than five hours. So, as well as you'll get paid, we have ...
