FXCracked Just4Forex TradeWithSam. Quick Links. They found that a majority of transgender and non-binary people experienced both negative financial and social impacts from the pandemic. Using crowdsourced data collection, Statistics Canada found important gender differences in the self-perceived mental health of individuals in Canada during the first wave of the COVID -1 9 pandemic. The Census release on families, households and marital status, which will take place on July 13, , will include analysis and data tables on couples.
In particular, there will be analysis of same-gender and different-gender couples, as well as couples composed of at least one transgender person or at least one non-binary person. Family and household characteristics and sociocultural and socioeconomic data from the Census released over the next months will continue to enrich the portrait of the transgender and non-binary populations in Canada.
The Canadian population is encouraged to download the StatsCAN app to view the census results. In April , Statistics Canada published new metadata standards for sex at birth and gender to better reflect the way the Canadian population self-identifies. Throughout the winter of , Statistics Canada held a public consultation on the update to the gender standard to ensure it remains relevant and meaningful for the communities of interest. The standards on sex at birth and gender were modified to reflect feedback received during this consultation.
The updated standards were published in October , and a "What we heard" report summarizing comments received during the public consultation will be published in the coming months. The sex at birth standard provides a classification variant with three categories male, female and intersex. However, for reasons related to the small size of the intersex population and the challenges in identifying intersex people, Statistics Canada does not currently collect specific information on intersex people in Canada.
Tables 1 and 2 present distributions of the Canadian population aged 15 and older living in a private household by sex according to data from the to censuses and sex at birth and gender using Census data. In , the number of people whose sex was male was very similar to the number of men. The same was observed among people whose sex was female compared with women.
These similarities can be explained by the relatively small size of the transgender and non-binary populations. Moreover, the distribution of the population aged 15 and older in private households by sex from to and sex at birth in was very similar between census years. In this article, certain gender non-binary terms were grouped based on their similarities e. For more information on collection and processing methods of responses to the "specify" option for the gender question, please refer to the Age, Sex at Birth and Gender Reference Guide, Census of Population, The term "Two-Spirit" is specific to some Indigenous peoples of North America see gender classification.
However, the Indigenous identity of individuals was not taken into account when coding answers to the "specify" option for the gender question. The number of "Two-Spirit" answers may be smaller if only Indigenous individuals were included. The definitions for terms describing non-binary gender are included in the Gender and Sexual Diversity Glossary , published by the Translation Bureau. In this release, the analysis of gender diversity results is limited to the population aged 15 and older even though the question was asked regardless of age, as children aged 14 and younger may not be fully aware of their gender identity or may not have defined it yet.
In the Census in brief: A generational portrait of Canada's aging population from the Census , Generation Z is defined as people born between and and aged 9 to 24 in May In this article, since the analysis is focused on the population aged 15 and older, Generation Z is redefined as those born between and and aged 15 to 24 in May To ensure the confidentiality of responses collected for the Census, a random rounding process is used to alter the values of released data.
As a result, when these data are summed or grouped, the total value may not match the sum of the individual values, since the total and subtotals are independently rounded. Today, Statistics Canada is releasing the second set of results from the Census of Population.
Several Census products are also available today on the Census Program web module. This web module has been designed to provide easy access to census data, free of charge. Analytical products include two releases in The Daily and two articles in the Census in Brief series.
Data products include the sex at birth and gender, as well as age and type of dwelling results for a wide range of standard geographic areas, available through the Census Profile and data tables. Focus on Geography provides data and highlights on key topics found in this Daily release and in the Census in Brief articles at various levels of geography. Reference materials are designed to help users make the most of census data.
They include the Guide to the Census of Population, , the Dictionary, Census of Population, , and the Census of Population questionnaires. Both the dictionary and the guide are updated with additional information throughout the release cycle. The Type of Dwelling Reference Guide, Census of Population, and Age, Sex at Birth and Gender Reference Guide, Census of Population, are also available. A fact sheet on gender concepts, Filling the gaps: Information on gender in the Census , is also available.
The Balancing the Protection of Confidentiality with the Needs for Disaggregated Census Data report was previously released in reference materials. Videos on census concepts can be found in the Census learning centre. Geography-related Census Program products and services can be found under Geography.
This includes GeoSearch , an interactive mapping tool, and thematic maps , which show data for various standard geographic areas, along with the Focus on Geography and Census Program Data Viewer , which are data visualization tools. Over the coming months, Statistics Canada will continue to release results from the Census of Population, and provide an even more comprehensive picture of the Canadian population.

Chart 1 The transgender and non-binary generation gap. Chart 2 Gender diversity is highest among to year-olds. Diversity within gender diversity: Most common terms to describe non-binary gender In this release, the term "non-binary" is used to describe all genders that are neither exclusively man nor woman, although individuals might self-identify with other terms.
In statistics , quality assurance , and survey methodology , sampling is the selection of a subset a statistical sample of individuals from within a statistical population to estimate characteristics of the whole population. Statisticians attempt to collect samples that are representative of the population in question.
Sampling has lower costs and faster data collection than measuring the entire population and can provide insights in cases where it is infeasible to measure an entire population.
Each observation measures one or more properties such as weight, location, colour or mass of independent objects or individuals. In survey sampling , weights can be applied to the data to adjust for the sample design, particularly in stratified sampling.
In business and medical research, sampling is widely used for gathering information about a population. Successful statistical practice is based on focused problem definition. In sampling, this includes defining the " population " from which our sample is drawn. A population can be defined as including all people or items with the characteristic one wishes to understand.
Because there is very rarely enough time or money to gather information from everyone or everything in a population, the goal becomes finding a representative sample or subset of that population.
Sometimes what defines a population is obvious. For example, a manufacturer needs to decide whether a batch of material from production is of high enough quality to be released to the customer, or should be sentenced for scrap or rework due to poor quality.
In this case, the batch is the population. Although the population of interest often consists of physical objects, sometimes it is necessary to sample over time, space, or some combination of these dimensions. For instance, an investigation of supermarket staffing could examine checkout line length at various times, or a study on endangered penguins might aim to understand their usage of various hunting grounds over time.
For the time dimension, the focus may be on periods or discrete occasions. In other cases, the examined 'population' may be even less tangible. For example, Joseph Jagger studied the behaviour of roulette wheels at a casino in Monte Carlo , and used this to identify a biased wheel. In this case, the 'population' Jagger wanted to investigate was the overall behaviour of the wheel i.
the probability distribution of its results over infinitely many trials , while his 'sample' was formed from observed results from that wheel. Similar considerations arise when taking repeated measurements of some physical characteristic such as the electrical conductivity of copper. This situation often arises when seeking knowledge about the cause system of which the observed population is an outcome. In such cases, sampling theory may treat the observed population as a sample from a larger 'superpopulation'.
For example, a researcher might study the success rate of a new 'quit smoking' program on a test group of patients, in order to predict the effects of the program if it were made available nationwide. Here the superpopulation is "everybody in the country, given access to this treatment" — a group which does not yet exist, since the program isn't yet available to all. The population from which the sample is drawn may not be the same as the population about which information is desired.
Often there is large but not complete overlap between these two groups due to frame issues etc. see below. Sometimes they may be entirely separate — for instance, one might study rats in order to get a better understanding of human health, or one might study records from people born in in order to make predictions about people born in Time spent in making the sampled population and population of concern precise is often well spent, because it raises many issues, ambiguities, and questions that would otherwise have been overlooked at this stage.
In the most straightforward case, such as the sampling of a batch of material from production acceptance sampling by lots , it would be most desirable to identify and measure every single item in the population and to include any one of them in our sample.
However, in the more general case this is not usually possible or practical. There is no way to identify all rats in the set of all rats. Where voting is not compulsory, there is no way to identify which people will vote at a forthcoming election in advance of the election. These imprecise populations are not amenable to sampling in any of the ways below and to which we could apply statistical theory. As a remedy, we seek a sampling frame which has the property that we can identify every single element and include any in our sample.
For example, in an opinion poll , possible sampling frames include an electoral register and a telephone directory. A probability sample is a sample in which every unit in the population has a chance greater than zero of being selected in the sample, and this probability can be accurately determined.
The combination of these traits makes it possible to produce unbiased estimates of population totals, by weighting sampled units according to their probability of selection. Example: We want to estimate the total income of adults living in a given street. We visit each household in that street, identify all adults living there, and randomly select one adult from each household.
For example, we can allocate each person a random number, generated from a uniform distribution between 0 and 1, and select the person with the highest number in each household. We then interview the selected person and find their income. People living on their own are certain to be selected, so we simply add their income to our estimate of the total.
But a person living in a household of two adults has only a one-in-two chance of selection. To reflect this, when we come to such a household, we would count the selected person's income twice towards the total.
The person who is selected from that household can be loosely viewed as also representing the person who isn't selected. In the above example, not everybody has the same probability of selection; what makes it a probability sample is the fact that each person's probability is known.
When every element in the population does have the same probability of selection, this is known as an 'equal probability of selection' EPS design. Such designs are also referred to as 'self-weighting' because all sampled units are given the same weight.
Probability sampling includes: Simple Random Sampling , Systematic Sampling , Stratified Sampling , Probability Proportional to Size Sampling, and Cluster or Multistage Sampling. These various ways of probability sampling have two things in common:. It involves the selection of elements based on assumptions regarding the population of interest, which forms the criteria for selection.
Hence, because the selection of elements is nonrandom, nonprobability sampling does not allow the estimation of sampling errors. These conditions give rise to exclusion bias , placing limits on how much information a sample can provide about the population. Information about the relationship between sample and population is limited, making it difficult to extrapolate from the sample to the population. Example: We visit every household in a given street, and interview the first person to answer the door.
In any household with more than one occupant, this is a nonprobability sample, because some people are more likely to answer the door e.
an unemployed person who spends most of their time at home is more likely to answer than an employed housemate who might be at work when the interviewer calls and it's not practical to calculate these probabilities.
Nonprobability sampling methods include convenience sampling , quota sampling , and purposive sampling. In addition, nonresponse effects may turn any probability design into a nonprobability design if the characteristics of nonresponse are not well understood, since nonresponse effectively modifies each element's probability of being sampled.
Within any of the types of frames identified above, a variety of sampling methods can be employed individually or in combination. Factors commonly influencing the choice between these designs include:. In a simple random sample SRS of a given size, all subsets of a sampling frame have an equal probability of being selected.
Each element of the frame thus has an equal probability of selection: the frame is not subdivided or partitioned. Furthermore, any given pair of elements has the same chance of selection as any other such pair and similarly for triples, and so on.
This minimizes bias and simplifies analysis of results. In particular, the variance between individual results within the sample is a good indicator of variance in the overall population, which makes it relatively easy to estimate the accuracy of results.
Simple random sampling can be vulnerable to sampling error because the randomness of the selection may result in a sample that doesn't reflect the makeup of the population.
For instance, a simple random sample of ten people from a given country will on average produce five men and five women, but any given trial is likely to over represent one sex and underrepresent the other. Systematic and stratified techniques attempt to overcome this problem by "using information about the population" to choose a more "representative" sample. Also, simple random sampling can be cumbersome and tedious when sampling from a large target population.
In some cases, investigators are interested in research questions specific to subgroups of the population. For example, researchers might be interested in examining whether cognitive ability as a predictor of job performance is equally applicable across racial groups. Simple random sampling cannot accommodate the needs of researchers in this situation, because it does not provide subsamples of the population, and other sampling strategies, such as stratified sampling, can be used instead.
Systematic sampling also known as interval sampling relies on arranging the study population according to some ordering scheme and then selecting elements at regular intervals through that ordered list. Systematic sampling involves a random start and then proceeds with the selection of every k th element from then onwards. It is important that the starting point is not automatically the first in the list, but is instead randomly chosen from within the first to the k th element in the list.
A simple example would be to select every 10th name from the telephone directory an 'every 10th' sample, also referred to as 'sampling with a skip of 10'. As long as the starting point is randomized , systematic sampling is a type of probability sampling.
It is easy to implement and the stratification induced can make it efficient, if the variable by which the list is ordered is correlated with the variable of interest. For example, suppose we wish to sample people from a long street that starts in a poor area house No. A simple random selection of addresses from this street could easily end up with too many from the high end and too few from the low end or vice versa , leading to an unrepresentative sample.
Selecting e. every 10th street number along the street ensures that the sample is spread evenly along the length of the street, representing all of these districts. Note that if we always start at house 1 and end at , the sample is slightly biased towards the low end; by randomly selecting the start between 1 and 10, this bias is eliminated. However, systematic sampling is especially vulnerable to periodicities in the list. If periodicity is present and the period is a multiple or factor of the interval used, the sample is especially likely to be un representative of the overall population, making the scheme less accurate than simple random sampling.
For example, consider a street where the odd-numbered houses are all on the north expensive side of the road, and the even-numbered houses are all on the south cheap side. Under the sampling scheme given above, it is impossible to get a representative sample; either the houses sampled will all be from the odd-numbered, expensive side, or they will all be from the even-numbered, cheap side, unless the researcher has previous knowledge of this bias and avoids it by a using a skip which ensures jumping between the two sides any odd-numbered skip.
Another drawback of systematic sampling is that even in scenarios where it is more accurate than SRS, its theoretical properties make it difficult to quantify that accuracy. In the two examples of systematic sampling that are given above, much of the potential sampling error is due to variation between neighbouring houses — but because this method never selects two neighbouring houses, the sample will not give us any information on that variation.
As described above, systematic sampling is an EPS method, because all elements have the same probability of selection in the example given, one in ten. It is not 'simple random sampling' because different subsets of the same size have different selection probabilities — e. the set {4,14,24, Systematic sampling can also be adapted to a non-EPS approach; for an example, see discussion of PPS samples below.
When the population embraces a number of distinct categories, the frame can be organized by these categories into separate "strata. First, dividing the population into distinct, independent strata can enable researchers to draw inferences about specific subgroups that may be lost in a more generalized random sample. Second, utilizing a stratified sampling method can lead to more efficient statistical estimates provided that strata are selected based upon relevance to the criterion in question, instead of availability of the samples.
