Inge Susanto and her husband Yudi Su-priady are natives and citizens of Indone[*59] sia, where they belonged to two minority groups: ethnic Chinese and Christian. ^[1] In 2002, the Immigration and Naturalization Service (INS) charged petitioners with removability, which they acknowledge. Petitioners applied for asylum, however, asserting that they suffered persecution in Indonesia on account of their ethnicity and religion.

At their hearing before an immigration judge (IJ), petitioners adduced as evidence of persecution, inter alia, the violent riots by Indonesia’s Muslim majority in 1998 against the Chinese minority, which resulted in many deaths, rapes, and serious injuries, and which prompted Susanto and her mother to wear face veils in public, so as to disguise their' ethnicity, and Susanto’s family to relocate from Jakarta to another part of the country for two months; the vandalization of the family home during their two-month absence from the capital, and the discovery upon their return that one of their Chinese neighbor’s daughters had been raped; an incident in 1998 during which two men confronted Susanto (then age 14) outside her school, called her a “Chinese snob,” and tried (but failed) to grope her; an incident during which Sus-anto and her mother were mugged at knifepoint on a city bus, and the mugger stated: “You Chinese, you die”; the discovery of an undetonated bomb at Susan-to’s church, and a subsequent bombing of the same church; and incidents in 1999 during which Muslim crowds threatened and threw stones at Susanto and her fellow worshipers.

The IJ denied petitioners’ asylum application, for failure to establish past persecution or a well-founded fear of future persecution in the event they were repatriated to Indonesia. See 8 U.S.C. § 1101(a)(42)(A); 8 C.F.R. § 208.13(b). Specifically, the IJ found that the alleged past incidents were not severe enough to constitute persecution, and that the prospect of future persecution was “small.” On appeal, the Board of Immigration Appeals (BIA) affirmed without separate opinion, and petitioners now appeal. See Olujoke v. Gonzales, 411 F.3d 16, 21 (1st Cir.2005) (noting that, on appeal from BIA’s summary affirmance, court of appeals directly reviews IJ decision).

We review the IJ decision only to determine whether its findings of fact that petitioners did not suffer from cognizable past “persecution” and did not confront a well-founded fear of future persecution are supported by “substantial evidence” in the administrative record. See Silva v. Ashcroft, 394 F.3d 1, 4 (1st Cir.2005).

Petitioners first assert that the IJ’s decision is unsupported because it fails to take into account the very serious incidents of ethnicity and religion-based persecution described by Susanto. Petitioners must bear the burden of proof as to their eligibility for asylum, see INS v. Cardoza-Fonseca, 480 U.S. 421, 423, 107 S.Ct. 1207, 94 L.Ed.2d 434 (1987), and we repeatedly have observed that harassment of the quality and degree experienced by petitioners simply does not compel a finding of persecution. See, e.g., Nelson v. INS, 232 F.3d 258, 263-64 (1st Cir.2002) (affirming IJ finding of no persecution even where petitioner was placed in solitary confinement and physically abused); see also Bocova v. Gonzales, 412 F.3d 257, 263-64 (1st Cir.2005) (same, two police beatings during a two-year period). The baseline rule is that past persecution requires “more than mere discomfiture, un[*60] pleasantness, harassment, or unfair treatment.” Nikijuluw v. Gonzales, 427 F.3d 115, 120 (1st Cir.2005). Although the harassment experienced by these petitioners certainly was ugly, discriminatory, and regrettable, they experienced no physical confinement and no serious physical injuries resulted.

Next, petitioners contend that the IJ erred in determining that they failed to establish a well-founded fear of future persecution because the IJ inappropriately confined his inquiry to whether the petitioners would be murdered or raped if they were to return, and required that petitioners prove more than a 10% risk of such future persecution. ^[2] The latter argument advanced by petitioners is premised on INS v. Cardoza-Fonseca, 480 U.S. 421, 107 S.Ct. 1207, 94 L.Ed.2d 434 (1987), where the Supreme Court noted that even as little as a 10% risk of occurrence might support a well-founded fear of future persecution. Id. at 431, 107 S.Ct. 1207. They contend that, contrary to the IJ’s interpretation of Cardoza-Fonseca, the Court did not suggest that the courts should utilize this 10% figure as an artificial benchmark. These arguments are unpersuasive as well.

The context of the IJ’s decision makes it clear that he did not mean to suggest that murder and rape were the only cognizable forms of future persecution. Rather, in juxtaposition to the alleged incidents of past persecution in this case, the IJ mentioned murder and rape simply as examples of the types of harm severe enough to constitute cognizable forms of future persecution. The IJ did not imply that only murder and rape rise to the requisite level of persecution.

Likewise, the IJ’s reference to Cardoza-Fonseca and the 10% formulation, read in context, does not provide a basis for reversal. While Susanto is correct that she is not required to show that her likelihood of suffering persecution is, as a mathematical matter, at least 10%, we do not take the IJ’s use of this formulation to require such a showing. The IJ’s mention of the formulation followed his statistical observation that Indonesia has “millions” of ethnic Chinese, whereas the casualties of the 1998 riots were in the “thousands” or “tens of thousands.” In this context, it is clear that the IJ simply intended to point out that the prospect of past and future persecution against these petitioners had been and would remain a “small one,” viz., considerably less than the 10% risk considered sufficient in Cardoza-Fonseca. The IJ never attempted to quantify the precise level of this “small” risk, nor does Cardoza-Fonseca require such precision. See Aguilar-Solis v. INS, 168 F.3d 565, 572 (1st Cir.1999) (citing Cardoza-Fonseca for its general holding that requisite risk is “somewhat less than the classic ‘more likely than not’ formulation,” and noting that “[bjeyond a tentative suggestion that a ‘reasonable probability’ of persecution may capture the essence of the legal standard, the Court has not been markedly more precise”).

These two challenged findings were supported by “substantial evidence” in the administrative record. The State Department Reports adduced by the government assert that the worst of the 1998 anti-Chinese violence occurred in the eastern parts of Indonesia (whereas Susanto lived in Jakarta, in the central region of the country), and that Indonesia, in response to intense international condemnation of[*61] the 1998 anti-Chinese riots, has taken serious remedial measures to reduce the risks of any recurrence. Indeed, Susanto herself testified that security officers are now posted at her church. Thus, it was entirely rational for the IJ to conclude that there presently exists but a small chance that petitioners would suffer serious harm were they to return to Indonesia. Moreover, the IJ reasonably concluded that, were petitioners threatened with such harm, they reasonably might relocate to a safer part of Indonesia, such as the areas with a Christian majority. Indeed, Susanto herself testified that the family fled to her uncle’s house in just such a safer region during the 1998 riots. See El Moraghy v. Ashcroft, 331 F.3d 195, 199 (1st Cir.2003) (noting that evidence of viable relocation option may undercut well-founded fear of future persecution); see also 8 C.F.R. § 208.13(b)(1)(i)(B).

Finally, petitioners now-argue, for the first time, that the IJ erred because he assessed the seriousness of the 1998 incidents experienced by Susanto as if she had been an adult, whereas a 14-year-old child may perceive an experience as persecutory, where an adult would not. She cites various guidelines for assessing the asylum claims of children. We do not address this issue, however, as these arguments were never raised before the BIA, thus are deemed waived on appeal, for failure to exhaust administrative remedies. See Opere v. INS, 267 F.3d 10, 14 (1st Cir.2001).

The petition for review is DENIED.
