How do Londoners feel about the ULEZ charge?

The Ultra Low Emission Zone (ULEZ) is going to be expanded to outer London boroughs on 31st August 2023. Anyone not driving a low emission vehicle will have to pay £10 a day to drive in those areas.

This will affect around 15% of car drivers and almost 50% of van drivers. These are primarily people driving older vehicles. (1)

Labour London mayor Sadiq Khan is enacting ULEZ. It has been blamed for Labour losing the recent Uxbridge by-election by just 500 votes.

Ironically for Labour this is a policy which affects the poor disproportionately. Anyone who could afford to buy a newer, lower emission vehicle would buy one, and drive it with no penalty.

Unfortunately for the environment and younger people this issue has become a battle ground for the coming 2024 election.

The Tories are now thinking of scrapping commitments to ULEZs in order to win votes. They are thinking of trashing environmental policies to try and stay in power.

But what do Londoners actually think about this issue?

What do Londoners think of Ultra Low Emission Zones?

There have been several polls on this issue. The results differ depending on how the questions about ULEZ are framed.

If you ask a question purely about ULEZ, then most people support the expansion. However, if you include reference to charges in relation to ULEZ then most people are against it.

This is a useful example of framing bias in social surveys.

ULEZ Survey, charges not mentioned

Question: “To tackle air pollution in the capital, the Mayor of London and Transport for London are proposing to expand the Ultra Low Emission Zone (ULEZ) London-wide. The proposed implementation date for this is 29th August 2023. Which, if any, of the following comes closest to your view?”

Support for ULEZ

ULEZ Survey: charges mentioned

Question: “To tackle air pollution, some places across the UK like London, are introducing charges in Low Emission Zones (sometimes called Ultra Low Emission Zones or ULEZ) where those who drive the more polluting cars or vehicles have to pay a fee or charge to drive into these areas. Would you support or oppose a similar ULEZ charge in your local area? “

Opposition to ULEZ

Attitudes to ULEZ Conclusions

I’d be inclined to say the question which mentions charges is a more accurate reflection of public opinion. This is because it includes more specific details so people can provide a more informed response.

We can also see from the above that lower social classes are more likely to be against ULEZ. This makes sense because these are the people who can’t afford to buy newer vehicles.

We also see that younger people are more in favour, which reflects attitudes to the environment more generally.

It is shameful that the Tories are prepared to use the environment as a political tool. They are sacrificing the future of younger people to win a few more seats in the hope of staying in power.

The fact that they are prepared to do this shows us they are no longer worthy to govern.

This is mainly relevant to the social research methods topic. It is a good example of how social surveys are more useful with more detailed questions.

YouGov Surveys – What the World Thinks?

The YouGov website is a great source for finding examples of social surveys and results from survey data.

Quantitative Data

 

YouGov is company which collects mainly survey data on a wide range of topics from people all over the world, and publishes it’s findings on a daily basis.

On their intro page they say ‘YouGov is a community of 4 million people around the world who share their views…. w’ere pretty sure its the largest daily updated database of people’s habits and opinions in the world’ – in addition to the structured survey data, some people also comment on the findings of said data, so you get a more qualitative feel added into the mix.

The data is very easy to access – for example below are YouGov’s latest findings on attitudes towards the children of illegal immigrants:

attitudes-to-immigration-uk

 

You can see from the above that we are pretty intolerant of illegal immigrants as a nation, which is one of the advantages of survey data.

You can also ‘drill down’ into the data and find correlations between attitudes and politics/ gender/ age and social class. Below we see that older people are less tolerant than younger people:

young-people-attitudes-immigration

The advantages and disadvantages of social surveys 

The big strength of this site is that it’s very accessible – you can very easily get some quick ‘facts’ about what people think about a lot of different topics, and you can easily see the correlations between attitudes and other variables such as class and gender.

The information contained in the site is also good for illustrating the limitations of survey data – you don’t really get any depth or explanation of why people hold these views (not even with the comments, because relatively few people comment).

Finally, I really like the fact that you get to see the specific question asked, so you can always bung a particular question, or set of questions on Socrative to check out the reliability with your students!

Social Surveys – Strengths and Limitations

Social Surveys are a quantitative, positivist research method consisting of structured questionnaires and interviews. This post considers the theoretical, practical and ethical advantages and disadvantages of using social surveys in social research. 

The strengths and limitations below are mainly based around surveys administered as self-completion questionnaires.

Theoretical Factors

Theoretical strengths of social surveys

Detachment, Objectivity and Validity

Positivists favour questionnaires because they are a detached and objective (unbiased) method, where the sociologist’s personal involvement with respondents is kept to a minimum.

Hypothesis Testing

Questionnaires are particularly useful for testing hypotheses about cause and effect relationships between different variables, because the fact that they are quantifiable allows us to find correlations.

For example, based on government statistics on educational achievement we know that white boys on Free School Meals achieve at a significantly lower level than Chinese girls on Free School Meals. We reasonably hypothesise that this is because differences in parental attitudes – Chinese parents may value education more highly, and they may be stricter with their children when it comes to homework compared to white parents. Good questionnaire design and appropriate sampling would enable us to test out this hypothesis. Good sampling would further allow us to see if those white working class boys who do well have parents with similar attitudes to those Chinese girls who do well.

Representativeness

Questionnaires allow the researcher to collect information from a large number of people, so the results should be more representative of the wider population than with more qualitative methods. However, this all depends on appropriate sampling techniques being used and the researchers having knowledge of how actually completes the questionnaire.

Reliability

Questionnaires are generally seen as one of the more reliable methods of data collection – if repeated by another researcher, then they should give similar results. There are two main reasons for this:

When the research is repeated, it is easy to use the exact same questionnaire meaning the respondents are asked the exact same questions in the same order and they have the same choice of answers.

With self-completion questions, especially those sent by post, there is no researcher present to influence the results.

The reliability of questionnaires means that if we do find differences in answers, then we can be reasonably certain that this is because the opinions of the respondents have changed over time. For this reason, questionnaires are a good method for conducting longitudinal research where change over time is measured.

Social surveys are a good method for measuring change over time.

Theoretical Limitations

Issues affecting validity – Interpretivists make a number of criticisms of questionnaires.

The Imposition Problem

The imposition problem is when the researcher chooses the questions, they are deciding what is important rather than the respondent, and with closed ended questions the respondent has to fit their answers into what’s on offer. The result is that the respondent may not be able to express themselves in the way that want to. The structure of the questionnaire thus distorts the respondents’ meanings and undermines the validity of the data.

Misinterpetation of questions

Interpretivists argue that the detached nature of questionnaires and the lack of close contact between researcher and respondent means that there is no way to guarantee that the respondents are interpreting the questions in the same way as the researcher. This is especially true where very complex topics are involved – If I tick ‘yes’ that I am Christian’ – this could mean a range of things – from my being baptised but not practising or really believing to being a devout Fundamentalist. For this reason Interpretivists typically prefer qualitative methods where researchers are present to clarify meanings and probe deeper.

Researchers may not be present to check whether respondents are giving socially desirable answers, or simply lying, or even to check who is actually completing the questionnaire. At least with interviews researchers are present to check up on these problems (by observing body language or probing further for example).

Issues affecting representativeness

Postal questionnaires in particular can suffer from a low response rate. For example, Shere Hite’s (1991) study of ‘love, passion, and emotional violence’ in the America sent out 100, 000 questionnaires but only 4.5% of them were returned.

All self-completion questionnaires also suffer from the problem of a self-selecting sample which makes the research unrepresentative – certain types of people are more likely to complete questionnaires – literate people for example, people with plenty of time, or people who get a positive sense of self-esteem when completing questionnaires.

Practical Factors

Slide showing the practical strengths and limitations of social surveys.

Practical Strengths of Social Surveys

Questionnaires are a quick and cheap means of gathering large amounts of data from large numbers of people, even if they are widely dispersed geographically if the questionnaire is sent by post or conducted online. It is difficult to see how any other research method could provide 10s of millions of responses as is the case with the UK national census.

In the context of education, Connor and Dewson (2001) posted nearly 4000 questionnaires to students at 14 higher education institutions in their study of the factors which influenced working class decisions to attend university.

With self-completion questionnaires there is no need to recruit and train interviewers, which reduces cost.

The data is quick to analyse once it has been collected. With online questionnaires, pre-coded questions can be updated live.

Practical Limitations

The fact that questionnaires need to be brief means you can only ever get relatively superficial data from them, thus for many topics, they will need to be combined with more qualitative methods to achieve more insight.

Although questionnaires are a relatively cheap form of gathering data, it might be necessary to offer incentives for people to return them.

Structured Interviews are also considerably more expensive than self-completion questionnaires.

Ethical Factors

slide showing the ethical strengths and limtiations of social surveys

Ethical strengths of surveys

When a respondent is presented with a questionnaire, it is fairly obvious that research is taken place, so informed consent isn’t normally an issue as long as researchers are honest about the purpose of the research.

It is also a relatively unobtrusive method, given the detachment of the researcher, and it is quite an easy matter for respondents to just ignore questionnaires if they don’t want to complete them.

Ethical Limitations

They are best avoided when researching sensitive topics.

Social Surveys – An Introduction to Structured Questionnaires and Structured Interviews

Social Surveys, conducted by various organizations, are standardized procedures to gather information from large populations. Using methods like questionnaires and structured interviews, they collect data on diverse topics. Prominent examples include the England and Wales Census and the British Social Attitudes Survey. These surveys can involve pre-coded or open-ended questions. While useful for broad social studies, surveys can impose researcher’s perspective or encounter interviewer bias, reducing their reliability and necessitating careful interview design and conduct.

A Social Survey involves obtaining information in a standardised way from large groups of people. The main survey methods are questionnaires and structured interviews.

A wide range of organisations carry out surveys, such as government departments, schools and colleges, businesses, charities, market research and consumer groups. You may well have been stopped in a high street by a market researcher asking your opinion about a new design of chocolate bar wrapper, or phoned by an independent polling company such as Mori asking you to do a brief survey on any number of social issues.

Examples of Social Surveys

Two well-known examples of Social Surveys in the United Kingdom include:

The England and Wales Census – The Census has taken place every ten years except for 1941. The sample for the Census is every household in England and Wales. The government conducted the last Census in 2021 and achieved a response rate of 97%. Most people completed it online during the Pandemic in the spring of 2021, but postal options were available. The Census asks basic information about who lives in the household, employment, education, religion, and health. You can find out more about the Census through the Office for National Statistics Census page.

The British Social Attitudes Survey – started in 1983 and has now been tracking social attitudes for 40 years. The main method of the BSA is face to face household interviews. However, the latest survey round in 2022 used a slightly different method. Because of the Pandemic, respondents had the option to do the survey by phone following an initial house call. The survey asks respondents about attitudes to a range of social issues: immigration, politics, gender and sexuality, social class, vaping, and marriage, for example.  

Types of Social Survey

Social Surveys are typically questionnaires designed to collect information from large numbers of people in standardised form. Researchers prepare surveys in advance of giving them to respondents, and so they have a ‘structure’ to them. Most questionnaires will have a high degree of structure, and it is difficult to see how one could have an ‘unstructured questionnaire’. Because of this questionnaires tend to be a very formal means of collecting data, allowing the researcher little freedom to ‘follow her nose’ unlike other methods such as unstructured interviews or participant observation.

Pre-coded, or closed question questionnaires are those in which the respondent has to choose from a limited range of responses. Two of the most common types of closed questionnaire are the simply yes/no questionnaire and the scaled questionnaire. These ask respondents to either strongly agree, agree, disagree, or strongly disagree with a particular statement. This later form of scaling is referred to as a ‘Likert Scale’ (basically a strength of feeling scale).

Examples of Likert Scale questions from the 2021 Census
Examples of Likert Scale questions from the British Social Attitudes survey.

One of the main problems of this type of questionnaire is the imposition problem, which refers to the risk that the research might be imposing their view, or framework on respondents rather than getting at what they really think about the issue.

Open-ended question questionnaires are less structured than pre-coded questionnaires. Although open-ended questionnaires will still usually have set questions, there is no pre-set choice of answers. Open questions allow individuals to write their own answers or dictate them to interviewers.

Different ways of administering surveys

The researcher has a choice of administering her questionnaire in a number of different ways. The most obvious difference choice is between whether respondents complete the surveys themselves, making it a ‘self-completion questionnaire’, or whether the researcher fills in the information, effectively making it a structured interview.

Some of the more obvious choices for ‘administering’ questionnaires include:

  • Sending questionnaires by post, or by email.
  • Simply putting the questionnaire online so that people can complete it.
  • Doing a structured interview in person, either on the street, house to house.
  • Doing the interview by phone.

Structured interviews with closed questions

One obvious way of improving the response rate to questionnaires is to conduct a face to face interview by paying a researcher to read out the questionnaire to the respondent and writing down their responses on their behalf. Having an interviewer present can also reduce misinterpretation of questions as respondents can ask for clarification where necessary and an interviewer can also target specific groups if necessary, as with much market research.

On the downside, structured interviews are more time consuming. One researcher can only do one interview at a time whereas thousands of people can complete a self completion questionnaire within minutes.

Structured Interviews and Interviewer Bias

At a more theoretical level, having an interviewer present opens up the possibility of interviewer bias occurring, where the presence of the researcher interferes with the results obtained. The social characteristics of the interviewer may affect the responses, depending on the age, gender and ethnicity of the researcher in relation to the respondent. If one is researching the prevalence of domestic violence against women, for example, one might reasonably expect a female victim to give different responses to a female researcher rather than a male researcher.

Each interviewer will have their own style of interviewing; right from selecting who they ask questions to if they are on the street, to the tone of voice, facial expressions, and pacing of the interview. Such differences can make it difficult for another researcher to repeat the exact conditions under which previous interviews took place. This will reduce the reliability of the results.

Training interviewers is one way to reduce interviewer bias, which is quite easy with structured interviews. These problems are likely to be more exaggerated with more qualitative unstructured interviews.
