Tables should be used to:

  • allow comparison of individual data values
  • present a very precise level of detail
  • show multiple units of measure (for example, measurements and percentages)
  • present only a small number of data values
  • show values and their sums

Types of table

Use a reference table (dataset) to make statistics available for future reference. These typically have a large number of entries covering a variety of different statistics broken down into different categories. They are supplied alongside the main commentary in an accompanying spreadsheet or dataset.

Create a presentation table to demonstrate a point that is being made in the text. These use data extracted from datasets, laid out so as to quickly reinforce the point. The design should ensure that patterns and exceptions are obvious at a glance.

Data order in tables

Group the data into meaningful subsets and make it clear in what order it should be read. Hierarchy and grouping can be shown by using white space and indenting column headings.

Grouped data

A table is made up of classification variables and data values, either of these can be used to order your table depending on the context.

If the table is not ranked by data value and the classification variables have a natural order, like age or geography, keep this order in the table.

Additional guidance is available on the recommended standard presentation order of statistics.

Put the variables that are most likely to be compared in columns, with the units, tens or hundreds beneath one another.

Where data are most likely to be compared between years

Where data are most likely to be compared between ages

Time should run from left to right or top to bottom.

Hierarchy and grouping

Show hierarchy and grouping using white space and by indenting column headings.

Column spacing

It’s easier to read columns of numbers if they are tightly spaced. Columns should use equal spacing, unless there is a specific reason for altering it. Split column headings over lines to save using wide columns, but choose a sensible place to put the line break.


The font type and size should match the font used in your publication. The font should be mono-spaced, with the same width for each character or digit, so that all the units align.

Bold text in tables

Don’t put numbers in bold as they will move from their correct alignment.




Number alignment

Always right-align headings and data in columns so that units, tens, hundreds and thousands are aligned and numbers of equal value are easily comparable.






Number rounding

Always use a consistent level of precision, but use the lowest level possible for the intended user.

For the “inquiring citizen”, that is, a broader, less statistical audience :


For the “information forager”, for example, a local politician making decisions about future council tax charges:


For the “expert analyst”, for example, in a statistical journal discussing the detailed methodology behind the estimation, or in a situation where reproducibility is important:


Effective rounding

Effective rounding can be used to communicate and present numbers so that they can be understood quickly and easily. Remove any unimportant or irrelevant information, but keep the detail in the data.

Look at whether there is a difference between the first numbers, second numbers, third numbers and so on. You should round the numbers for comparison to two effective digits.

When using effective rounding you may need an extra level of rounding when a value is small enough that the detail is removed when using two effective digits. If the value is not important it could be removed from the table. If it is important the level of effective rounding should be adjusted to an appropriate level.

Totals can go at the top or the bottom of a table, depending on their relevance and importance.

If your data are hierarchical, positioning the totals at the top can help emphasise that the total is broken down.


Use the same measure across all variables where possible.

Make it clear if different measures, for example measurements and percentages, are being used in the same table.

Shading, gridlines and other lines

Use lines and shading sparingly. Use subtle colours or greyscale. Make sure the shading doesn’t distract from the data.

Shading can be used to track data across rows but also to highlight specific values.


Put the units as a header in the top right corner of the chart. Use subheadings if the units change within a chart.

Titles and subtitles

Titles should be clear, concise and explain clearly what the table is about and what it measures. This description is known as the statistical measure and is followed by the geography and time period.

Table 3: Percentage of children in workless households, UK, 2013 and 2018

Include a descriptive main title if the table has a clear trend that lends itself to it. Follow the style for chart titles and write a title that is descriptive and tells the trend of the data or highlights the main story in no more than 10 words.

When using a descriptive main title, place the statistical measure, geography and time period in the subtitle.

Three-month growth and contributions to GDP growth, UK, March to May 2019


Use letters to annotate numbers and numbers to annotate words or letters.


Position the explanation of the annotations underneath the table.

Annotations should be slightly smaller than the table font.


If the data within your publication are from multiple sources list the individual data source(s) beneath each table.

If all data within your publication are from the same data source reference it in the main body text.
