Primary data is is data that has been observed or collected first hand
In statistics, data collection methods can be broadly categorized into primary and secondary methods. Primary data collection involves gathering new data directly from sources through techniques such as surveys, experiments, interviews, and observations. Secondary data collection, on the other hand, involves analyzing existing data that has been previously collected, such as databases, reports, and academic papers. Both methods aim to ensure data is accurate, reliable, and relevant to the research question at hand.
ways of presenting data in statistics
All statistics are data because all statistics are formed of numbers and numbers are a type of data (numrical). But not all data is statistics because not all data is numbers, it can also be words, pictures etc. It's like saying all apples are fruit but all fruit are not apples.

The answer is generally no. I note there is no hard and fast definition of the field of statistics. The definition of the field or discipline of statistics is not to reduce the number of values in the set of collected data. An objective of statistics is to characterize or add meaning to the collected data, through calculated values of the data. In this sense, statistics summarizes the data.

how is data collected and used for the purpose of national statistics
descriptive statistics-quantitavely describe the main features of a collection of data. Descriptive statistics are distinguished from inferential.Statistics(or inductive statistics),in that descriptive statistics aim to summarize a data set,rather than use the data to learn about the population that the data are thought to represent.
