    The Short Form asks only about number of people living in the house, their names, ages, relationship to head of house, and for some bizarre reason, if they are Hispanic or not. Not to be too politically incorrect, but when I was a Census taker in 1980, minorities constituted the overwhelming bulk of my 'mop-up' efforts, and like as not they would not reveal a thing to me when I asked them those simple questions. Some kicked me off of their property, refusing even the most basic questions ('do you live here?'). I think they trust their government less than white folk, at least in this instance.

    But now, in part thanks to the internet, what the US Census can collect on an Individual is much less than what a corp can get simply by asking.

    The Long Form is fillied with innocuous questions like how long it takes to get to work and if you can speak a different language. Even though they ask how much you make and how much your property is worth, that's not a whole lot different than the questionnaires you routinely get from, say, Yahoo! or Amazon.

    What the government Does do better than the corps is survey Each and Every household in the country, creating a valuable aggregated dataset that shows demographics and such. But they publish this information and make it available as a govt service.

    So I really don't see any need to panic here. In fact, the article is not about what it says its about. If you read the whole article you discover that the intro is just a hook: it's not about them giving your data to a corp, its about them blurring individual stats to Preserve the integrity of individuals.

    The actual Enumeration shall be made within three Years after the first Meeting of the Congress of the United States, and within every subsequent Term of ten Years, in such Manner as they shall by Law direct.

    IOW, the "actual Enumeration" refers to the process of taking the Census, and does not mean that only a direct counting of individuals is allowable. IMO the recent Supreme Court ruling to the contrary was exactly the same kind of political decision that resulted in us getting our current president. That said, the Constitution says that the Census must be performed in order to apportion seats in the House of Representatives, but it does not exclude its use for other purposes. In fact, it says that it is to be carried out as Congress directs, so Congress clearly has the right to design the Census as it sees fit.

    To give a little bit more away, the primary use of sampling being contemplated was actually targeted at non-respondents. The problem here is that while you could follow up on most non-respondents very easily, there are a lot of them, so it takes time. And, the more time that passes before you follow-up, the worse the data get, and what you really end up with is a systematic undercount.

So in rural Minnesota the one hispanic family is dropped replaced with a dash and a family is added to the 'white' category. There are theoretical attacks possible on this sort of data, especially where other tables are published. There are no examples of citizens complaining that their particular information has been disclosed. The second category of data are called 'public use files'. This is a sample of 1% of the forms, but with little or no geographic data. So in this file you can see that one person had this income category and that race and that age etc, through all the data in the census form. But you only know the state of residence. So you couldn't locate a particular individual. And the categories are wide enough that there would be multiple people with the same information, and census has computer programs to make sure that is the case.

They're deliberately fuzzing the data to remove individually identifying data, and even taking steps that may decrease it's usefullness (like letting it out in bigger aggregate blocks) in order to make it even harder. Perhaps the best quote was at the end of the article:

    The re-identification process is highly complex and doesn't have a high yield: In a Census Bureau test, only 10 percent of survey participants could be re-identified. But that is enough for the bureau to be concerned.

    "I think many people feel they could probably obtain information easier from some other source than trying to obtain it from a census file," says the bureau's Ms. Zayatz, "but we're still very protective."

    The U.S. Constitution says the purpose of the Census is to make an "actual enumeration." That is, to take an accurate count of Americans for the purpose of apportioning congressional districts. But the federal government has gone far beyond that mandate. The long version of the Census -- which one in every six households will receive -- contains a whopping 52 questions. That's 51 more than the Constitution requires. Maybe that's why compliance with the Census had plummeted to just 65% by 1990.

    Unfortunately, the government has ways of making you talk. Title 13, Chapter 7 of the U.S. code mandates a $100 fine for those who decline to answer Census questions. What kind of government demands, under penalty of law, reams of personal data -- including racial characteristics -- from its citizens? Ours does.

N years of school? How many bedrooms and bathrooms in the house? How many kids, and what ages?" - The information about kids alone can easily be correlated with school records, and the housing information with real estate tax and building inspection records. And it's even easier for government officials to do that than for businesses. Census tracts are small enough that the number of couples where the husband is Guatemalan and the wife Salvadoran and the kids are boy 12 and girl 10 are likely to be just 1.

  74. Obscuring data using graph theory by mtsang · · Score: 3

    One application of the famous min cut/max flow algorithm in graph theory (wooo!) is to consistently round matrix entries. i.e. (tricky definition) The rows sums and column sums of the rounded elements in the matrix are equal to the rounded row and column sums of the unaltered elements of the matrix.

    I hear you asking. Who cares?

    One application of this sort of matrix rounding is
    publishing confidential survey data. Rounding can disguise the data, so that it is not traceable to any particular individual.

    The reference below describes that the class of matrix rounding problems is equivalent to the flow problem in certain capacitated network flow models. Feasible flows can be found using the 'min cut/max flow' algorithm. The author proves that there is always a feasible solution for a subclass where marginal totals are uniformly confined.

    reference:
    Management Science, Vol. 12, No. 9, May 1966
    Bacharach, Michael. "Matrix Rounding Problems"

    since it is an old reference, I will attempt to convey the setup. The network is constructed as follows:

    The matrix to round, A, has individual entries, A(ij) arranged in rows and columns...

    Make a set X, consisting of a node, i, for each row in the matrix. Make a set Y consisting of a node, j, for each column in the matrix.
    Add an arc (i,j) representing each matrix entry A(ij). (Note X union Y is a bipartite graph)

    Add a source node s and attach it to each element in X, and a sink node t and attach it to each element in Y, the resulting arcs (s,i) represent each row sum and arcs (j,t) each column sum. The lower and upper bounds for all arcs should correspond to the lower and upper rounding limits of the original matrix entry, or the rounding limits for each row/column sum as appropriate.

    Any feasible (integer) flow from s to t, will correspond to an acceptable (integer) rounding of values. (And a maximum flow will give us a feasible flow.)

By the third, you're ignoring it, and starting to get stuff from marketers who guessed less well what your interests are.

    All censuses worldwide only release summary detail for various sizes of geographic areas, and they release detailed info only for larger areas (eg detailed crosstabs are available at county level and state level, whereas at zip code level only very basic info is relased).

    Generally any number which is less than a lower limit (typically 15) is ALWAYS rounded to 0, and all other numbers are statistically rounded (eg Aus census rounds to multiples of 3, that is 37 is rounded to 36 two-thirds of the time, and to 39 one-third of the time). In addition to this automated pass, the data is hand-massaged by statisticians to obscure anything else that they think may identify individuals.

    So some of the examples quoted above (eg "the number of families with one Asian parent, one Jewish parent and 4 children is 1") are pure and simple wrong - census summary data just does not make this information available.

    Remember that some of the first "computers" (mechanical tabulators) were actually built for the US census in 1890.
