Now you have come to the page, Choose variable. This page give you the oportunity to select which variables and values you want to display in your result of the table. A variable is a property of a statistical unit. The page is divided into several boxes, one for each variable, where you can select values by click to highlight one or more values. It always starts with the statistics variable which is the main value counted in the table.
Navigating with keyboard and screenreader. Select multiple object in row: SHIFT+arrow down/up. To select a single value in the listbox: Windows:Hold Ctrl + arrow down. Then release Ctrl and press space. Repeat. Mac:CMD+arrow down/up. Then release CMD and press spacebar. Repeat. (Works only in Chrome, not in Safari). To exit listbox with values selected, press TAB-key.

Period life expectancy estimates represent the average number of years a person can be expected to live according to the mortality experience of the entire population in a single-year. These estimates are calculated using age-specific death rates for a single-year (e.g. for a period life expectancy at age 70 in 2025, we would use projected mortality rates in 2025 for ages 70, 71, 72 and so on). Period life expectancies are often criticised due to an assumption that mortality rates remain fixed throughout the remainder of a person's life. If, as expected, mortality improves over time, period life expectancies will underestimate expected lifespans. Cohort life expectancies (Table 12889) are therefore considered a more realistic measure of how long a person of a given age at a given time will be expected to live on average.
The period life expectancy estimates in the population projections differ somewhat from the period life expectancies in the general population statistics (maximum 0.5 years). In the projections, the estimates of period life expectancy are based on age at the end of the year and not at time of death, as they are in the general population statistics. Furthermore, the projections apply a different model (an exponential model) in the calculations of the probabilities of death.
